Mathematics and Applications of Branes in String and Mtheory
http://sms.cam.ac.uk/collection/1202251
Mtheory is an 11dimensional quantum theory of gravity which, in addition to gravitons and other particlelike excitations, includes extended objects known as membranes and five branes. Though a complete definition of Mtheory is not yet known, it is proposed as a nonperturbative formulation of superstring theory and as such is a compelling candidate for a unified theory of the fundamental particles and forces in Nature. Much has been learned about Mtheory through its symmetries and its relation to supergravity and string theory and this has in turn led to important results in superstring theory and quantum gauge theory.

Quantum Cosmology tackles the quantum description of the early universe. It is aimed as an accessible primer that covers the basics, critically discussing ideas and concepts that comprise our current knowledge. The scope for analyzing quantum cosmological models within a supersymmetric framework is pointed.
As much as possible, it summarizes what we know, what we think we know and what we think we do not know on an equal footing. It is focused for ‘young’, inquisitive minds eager to embark on indepth research in this field. It is hoped to suggest the tools researchers will need to go on their own, pushing them to ask the right questions rather than seek definitive answers.

We have recently calculated the superconformal index on 5d N=1 supersymmetric theory with SU(2) gauge group and N fundamental hypermultiplets in the conformal limit where the gauge coupling goes to infinite. This index shows as expected that the global symmetry in the conformal limit is enhanced from the flavor SO(2N) symmetry and the global U(1) symmetry for the instanton number to the exceptional group E(N+1).

In the last few years a wealth of novel properties of N=2 supersymmetric gauge theories has been uncovered. In particular, much has been learned about the strong coupling limits of these gauge theories through a dual twodimensional perspective in terms of Riemann surfaces. In this talk I will discuss a quantitative check of this 4d2d correspondence by computing the instanton partition function of an SU(2) gauge theory that is associated to a higher genus Riemann surface and its corresponding conformal block. This exercise will reveal a better understanding of the correspondence between fourdimensional instanton partition functions and twodimensional conformal blocks.

There has been a lot of efforts during the last decade in order to provide a supergravity realisation of inflation. This is of crucial importance if one look at supergravity as the bridge connecting the effective field theory of inflation and a possible UV complete theory like string theory. Within a supergravity theory the inflationary dynamics is tightly constrained. I will discuss a particular kind of geometric constraints which arise by considering particular directions on the scalar manifold, namely the ones which are singled out by the process of supersymmetry breaking (the so called sGoldstino’s). As an example I will consider the constraint in the case of N=1, Fterm inflation.

Tuesday 06 March 2012, 11:3012:30
We construct a nonAbelian gauge theory of chiral 2forms (selfdual gauge fields) in 6 dimensions with a spatial direction compactified on a circle of radius R. It has the following two properties. (1) It reduces to the YangMills theory in 5 dimensions for small R. (2) It is equivalent to the Lorentzinvariant theory of Abelian chiral 2forms when the gauge group is Abelian. Previous nogo theorems prohibiting nonAbelian deformations of the chiral 2form gauge theory are circumvented by introducing nonlocality along the compactified dimension.

The past several years have seen dramatic progress in our understanding of scattering amplitudes, particularly in supersymmetric gauge and gravity theories. Theoretical advances including the discovery of rich mathematical structure and hidden symmetries have led also to practical advances which in many cases render previously impossible field theory calculations trivial. I will review these and recent related developments on correlation functions and Wilson loops in supersymmetric YangMills theory.

We propose a simple stringy mechanism that prefers metastable vacua with a small cosmological constant. We argue the generic probability distribution for the metastable vacua which peaks with a divergent behavior at the zero value of cosmological constant. Then we illustrate this in a model of type IIB string theory, though the suppression in the model is modest.

In ten and fourdimensional supergravities, the descriptions of nongeometric configurations are different. In the former, nongeometry arises as naively nonsingle valued supergravity fields. In the latter, new terms, coming from nongeometric Q and Rfluxes, appear in the fourdimensional potential. In this talk, it is shown that a tendimensional field redefinition results in a Qflux term in the NSNS Lagrangian. This change of field basis is inspired by generalized geometry. We argue that this new field basis provides a good description of certain nongeometric configurations. In particular, using the new basis, a dimensional reduction can be performed, in which the Qflux term gives rise to the expected term in the fourdimensional potential. We also discuss the global issues of this setup.

We study cosmological solutions in the effective heterotic string theory with \alpha'correction terms in string frame. It is pointed out that the effective theory has an ambiguity via field redefinition and we analyze generalized effective theories due to this ambiguity. We restrict our analysis to the effective theories which give equations of motion of second order in the derivatives, just as ``Galileon" field theory. This class of effective actions contains two free coupling constants. We find de Sitter solutions as well as the powerlaw expanding universes in our fourdimensional Einstein frame. The accelerated expanding universes are always the attractors in the present dynamical system.

Amplitudes and correlation functions have rich geometric structure in twistor space.

If there is enough time, I will discuss recent progress with gravity ampltiudes.

We study the complexified three point amplitudes, the basic building blocks for helicity amplitudes, for various six dimensional supersymmetric theories. In particular, we construct the amplitudes for the (2,0) theory, the worldvolume theory on coincident fivebranes in M theory, and discuss the implications for the dynamics of these mysterious theories.

We describe an efficient algorithmic test for the Swiss Cheese property in CalabiYau threefolds, which is typically considered in the context of moduli stabilization in Large Volume Scenarios of type~IIB flux compactifications of string theory. The algorithm recasts the issue of moduli stabilization at large volume into the language of algebraic geometry, thereby allowing for a large scale computational analysis. Preliminary results of a scan of CalabiYau three folds with small Hodge numbers will be presented.

First I discuss anomalies in heterotic compactifications. I argue that anomalies will generically not be universal, and illustrate this point by an explicit example of a heterotic orbifold blowup. Then, I investigate the origin of discrete (R and nonR) symmetries on smooth CalabiYau manifolds via an GLSM approach.

Antibranes in the deformed conifold are used for example to construct de Sitter vacua. In the probe approximation, they lead to a metastable state. I will present work done over the last three years to go beyond the probe approximation by taking into account the backreaction of the antibranes. To be, or not to be (a metastable state), that is the question. We are pinning down the answer.

Maximally supersymmetric string theory compactified on ddimensional torus is invariant under the nonperturbative Uduality groups E_{d+1}(Z). We will present the construction of the automorphic functions relevant for the supersymmetric protected BPS interactions in the lowenergy expansion of maximal supersymmetric effective action in various dimensions. We will show that the support of the nonvanishing Fourier coefficients for these automorphic form is given by the expected BPS conditions one can derive from the supersymmetric conditions.

Flux compactifications are an important building block for obtaining (semi)realistic string theory vacua. Conventional H and geometric flux are rather wellunderstood in this setting, however, nongeometric fluxes are understood to a far lesser degree.
In this talk, it is first reviewed how certain fluxes can be treated as the torsion of a connection, and how gravity theories can be formulated via the Palatini formalism. Next, this formalism is extended to higher orders in the curvature leading to constraints on the fluxes, which are then interpreted as Bianchi identities.

In this talk we discuss the complete classification of halfsupersymmetric branes in toroidally compactified IIA/IIB string theory in terms of representations of the Tduality group. We show that the branes of tendimensional IIA/IIB string theory must satisfy, upon toroidal compactification, specific wrapping rules in order to reproduce the number of supersymmetric branes in lower dimensions. The realisation of these wrapping rules suggests that IIA/IIB string theory contains a whole class of generalised KaluzaKlein monopoles. We find examples of Tduality representations of branes in lower dimensions, suggested by supergravity, of which none of the component branes follow from the reduction of any brane in tendimensional IIA/IIB string theory.

String compactifications incorporating nonvanishing Hflux have received increased attention over the past decade for their potential relevance to the moduli stabilization problem. Their internal spaces are in general not Kähler and, therefore, not CalabiYau. In the heterotic string an important technical problem is to construct gauge bundles on such spaces. I will present a method of how to explicitly construct gauge bundles over homogeneous nearlyKähler manifolds of dimension six. These bundles solve the heterotic string including first order alpha' corrections and allow for nonvanishing flux. I will also discuss some of the arising implications for model building.

Smith, D (University of Durham)
Wednesday 01 February 2012, 16:0017:00
Motivated by considering M2branes ending on M5branes, we consider the ABJM theory with a boundary. The addition of a boundary to a ChernSimons theory is nontrivial, in particular the bulk action is only gauge invariant up to a total derivative. For pure ChernSimons theories it is possible to impose boundary conditions which leads to the wellknown relation to WZW models. However for ChernSimons plus matter theories, the situation is more complicated. Instead, we show how to add boundary degrees of freedom to restore the gauge symmetry, and this turns out to also lead to a type of WZW model on the boundary.

We investigate ChernSimons theories coupling to vector matter. These kinds of models are quite interesting in the following sense. Firstly, they provide us with infinitely many interacting conformal field theories (CFT) with Lagrangian description, which enables us to study CFT in a direct calculation. Secondly, they are likely to be dual to higher spin theories in AdS4 beyond the conjecture by KlebanovPolyakov. After a belief introduction of this background, I will talk about U(N) ChernSimons theories coupling to vectorlike (fundamental/antifundamental) matter(boson or fermion). It turns out that these kinds of models can be exactly solved in the 't Hooft limit by employing a standard large N technique. I will explain the details on this when the matter includes pure fermion or boson. If time permits, I will talk about the case including both in a supersymmetric way, which is work in progress.

Lines of largeN conformal fixed points with and without supersymmetry are plentiful in three dimensions, thanks in part to the quantization of the ChernSimons level k. Such theories are interesting for a variety of reasons, most importantly for their potential role as holographic dual descriptions of quantum theories of gravity in AdS4. In this talk, we will study a particularly simple and instructive nonsupersymmetric example  U(N) ChernSimons theory coupled to fundamental fermions. As we shall illustrate by calculating the free energy of the theory on R2 at finite temperature for all values of the 't Hooft coupling lambda=N/k, this theory turns out to be surprisingly tractable in the largeN limit.

Very generic string/M theory assumptions can lead to nontrivial phenomenologies that can be tested at the LHC. The branching fraction to the 3rd family quarks of the gluino decay should be enhanced, leading to multilepton and/or multibjet signatures. On the other hand, chargino could have long enough lifetime to produce disappearing tracks in the detector.

Heterotic orbifolds provide a simple, globally consistent framework in which one can obtain the MSSM particle spectrum with no chiral exotics from string theory. In order to understand the dynamical aspects and phenomenology of these compactifications, such as the decoupling of vectorlike exotics, moduli stabilization, particle masses and couplings, we must compute the couplings in the corresponding low energy effective field theory.
We study Lpoint string correlation functions and thus derive string selection rules, which determine the allowed couplings in the superpotential of the low energy effective supergravity theory.

De Sitter vacua in type IIB / Ftheory by Kahler uplifting
Rummel, M (Universität Hamburg)
Tuesday 26 June 2012, 15:0015:15
We derive a sufficient condition and present explicit examples based on toric geometry for realizing metastable de Sitter vacua with small positive cosmological constant within type IIB string theory / Ftheory flux compactifications with spontaneously broken supersymmetry. There are a number of `lamp post' constructions of de Sitter vacua in type IIB string theory and supergravity. We show that one of them  the method of `K\"ahler uplifting' by Fterms from an interplay between nonperturbative effects and the leading α′correction  allows for a more general parametric understanding of the existence of de Sitter vacua. The result is a condition on the values of the flux induced superpotential and the topological data of the CalabiYau compactification, which guarantees the existence of a metastable de Sitter vacuum if met. Our analysis explicitly includes the stabilization of all moduli, i.e. the Kahler, dilaton and complex structure modu li, by the interplay of the leading perturbative and nonperturbative effects at parametrically large volume.

Dirac gauginos and unification in Ftheory
Davies, R (University of Oxford)
Wednesday 27 June 2012, 17:1517:30
In the MSSM, the gauginos are assumed to acquire Majorana masses after supersymmetry breaking. If the light spectrum is extended slightly to include chiral multiplets in the adjoint representation of the gauge group, they can instead acquire Dirac masses by pairing up with the fermionic components of these multiplets. Dirac gauginos have several interesting properties, not least that they can be significantly heavier than Majorana gauginos, without paying any price in naturalness; this becomes particularly interesting in the light of the null results of the 2011 LHC searches for superpartners. One good reason for a theory to contain Dirac gauginos is if it has an unbroken (approximate) Rsymmetry. In string theory, the construction of models with adjoint chiral fields and (optionally) an unbroken Rsymmetry poses different problems to constructing the MSSM, especially as the gauge couplings no longer unify unless further matter is present. I will discuss solutions to some of these problems within the context of Ftheory.

Discrete gauge symmetries in discrete orientifolds
Schellekens, AN (National Institute for Subatomic Physics (Nikhef))
Friday 29 June 2012, 09:3510:10
We study the origin of discrete gauge symmetries from open string sector U(1)'s in orientifolds based on rational conformal field theory. By means of an explicit construction, we find an integral basis for the couplings of axions and U(1) factors for all simple current MIPFs and orientifolds of all 168 Gepner models, a total of 32990 distinct cases. We discuss how the presence of discrete symmetries surviving as a subgroup of broken U(1)'s can be derived using this basis. We apply this procedure to models with MSSM chiral spectrum, concretely to all known U(3)xU(2)xU(1)xU(1) and U(3)xSp(2)xU(1)xU(1) configurations with chiral bifundamentals, but no chiral tensors, as well as some SU(5) GUT models.

I will show how the equations of motion of double field theory can also be derived as the oneloop background field equations of a double sigma model, both being the vanishing of the generalised Ricci tensor. This raises the possibility of deriving higher order corrections to double field theory from a sigma model approach.

It is well known that dimensional reductions of elevendimensional supergravity have unexpected hidden symmetries. E_d(d)xR^+ genealised geometry provides a unified geometrical formulation of the internal sector of the theory, in which these symmetries appear naturally as structure groups. The construction is exactly analogous to ordinary Riemannian geometry, but with an enlarged tangent space. In particular, using the analogue of the LeviCivita connection, the bosonic action and equations of motion can be expressed neatly as Einstein gravity for a generalised curvature tensor. Supersymmetry also appears in the process and the fermionic sector can be concisely reformulated in terms of the generalised connection. The talk will review the details of this formalism as well as discussing some explicit examples in particular dimensions.

The AdS/CFT correspondence of string theory offers the hope of direct, mathematically precise and systematically correctable study of strongly coupled quantum systems. Progress toward this goal will be described in the context of a simple example: the probe Dbrane dual of a class of relativistic field theories which resemble the description of graphene by relativistic fermions. A hypothesis that graphene can be such a strongly correlated quantum fluid and at the same time exhibit behaviours which are well modeled by noninteracting relativistic fermions will be discussed as well as some interesting new phases of matter which are suggested by the Dbrane construction.

By threealgebra ABJM theory I refer to any \N=6 supersymmetric ChernSimons matter theory. In this talk I show that if a threealgebra ABJM theory has a covariantly constant unitary monopole operator carrying two symmetric threealgebra indices, then this implies that this ABJM theory has hidden N=8 supersymmetry.

In the last decade, a framework in which string dualities are implemented at the supergravity level has been developed, i.e., the socalled embedding tensor formalism. However, the connection between this formalism and string theory realisations remains still obscure since most of the supergravities obtained by using the embedding tensor formalism correspond to very exotic (non)geometries in the string side.
In this talk we consider type II flux backgrounds compatible with the absence of brane sources, and construct their explicit embedding into maximal D=4 supergravity. This enables us to investigate the critical points, mass spectra and gauge groups of such "exceptional" backgrounds in a systematic way. We will chart the landscape of vacua in some specific setups which are relevant from the string theory viewpoint and discuss the issues of stability and supersymmetry at those vacuum solutions. Finally we will point towards some natural extensions of the results.

We show that partition functions of N=2 theories on the squashed 3sphere can be factorized into pairs of vortex theories defined on the two copies of R^2 x S1, corresponding to the two degeneration limits of the ellipsoid. We comment on how the ellipsoid partition function appears to provide the modular invariant nonperturbative completion of the vortex theory. We conclude with the geometrical engineering of the vortex theory.

Despite AdS5 S5 being selfdual under a combination of bosonic and fermionic Tdualities, the same has yet to be said for AdS4 CP3. However, evidence from D=3 scattering amplitude calculations hint strongly at some selfduality. We explain the obstacles in the context of ppwaves and the D1D5 nearhorizon and comment on whether betadeformed SYM inherits the same symmetries.

We show by explicit construction that for every solution of the incompressible NavierStokes equation in p+1 dimensions, there is a uniquely associated "dual" solution of the vacuum Einstein equations in p+2 dimensions. We consider both a "nearhorizon" limit in which Σc becomes highly accelerated, and a longwavelength hydrodynamic limit. We show that the nearhorizon expansion in gravity is mathematically equivalent to the hydrodynamic expansion in fluid dynamics, and the Einstein equation reduces to the incompressible NavierStokes equation.

Using M/Ftheory duality, I will relate the quantization of the Gflux in Mtheory to the one of the gauge flux on type IIB D7branes prescribed by FreedWitten anomaly cancellation. The correspondence is shown for all unitary and symplectic Kodaira singularities, by explicitly constructing appropriate 4cycles in the Mtheory elliptic fourfold, which are able to detect the global anomaly.

Fluxbrane Inflation
Kraus, S (Universität Heidelberg)
Tuesday 26 June 2012, 16:1516:30
Fluxbrane inflation (arXiv:1104.5016) is a recently proposed stringy realisation of Dterm hybrid inflation, featuring some appealing phenomenological characteristics. In contrast to other brane inflation models, fluxbrane inflation has a naturally flat inflaton potential at leading order and thus does not rely on strong warping or an extremely anisotropic compact space. Additionally, the scenario contains a mechanism which allows one to avoid the clash with observational bounds due to cosmic string production rather easily. In my talk, I will present the most interesting aspects of the model and, furthermore, discuss recent progress and new challenges regarding moduli stabilisation (in the context of the LARGE volume scenario) as well as the impact of higherorder corrections on the flatness of the inflaton potential.

We discuss the effective theory of Ftheory compactifications by using the Mtheory dual. Two main results are highlighted: (1) the chiral index of a 4D Ftheory compactification can be determined by fourform flux when comparing 3D ChernSimons theories at one loop, (2) the inclusion of warping effects due to fluxes in Mtheory is crucial to determine corrections to the Ftheory effective theory even if in the latter warping effects can be neglected.

The leading singularities of ABJM amplitudes are given by the residues of an Orthogonal Grassmanian. I will discuss how this information controls the multiloop amplitude, revealing an interesting relation between 4D N=4 SYM and ABJM. The behavior of the residues under complex deformation encodes, to the first order, the recent kinematic/threealgebra duality.

I discuss recent progress in the description of G4 gauge fluxes in Ftheory compactifications on CalabiYau fourfolds. Such fluxes are important from the perspective of Ftheory model building, where gauge fluxes are required for example for the generation of chiral matter. An explicit dictionary between a class of factorisable G4 fluxes in certain Ftheory compactifications and corresponding diagonal U(1) fluxes in Type IIB orientifolds sheds new light on the uplift of Type IIB vacua to Ftheory. This global description of gauge fluxes in Ftheory also allows for the evaluation of selection rules for M5instantons to contribute to the superpotential.

The duality is found by using both the SeibergWitten formalism and the topological vertex formalism. The duality map between the gauge theory parameters will be given. I will also discuss some implications of this duality in the context of the AGT conjecture.

Fourdimensional supersymmetric type II string theory vacua can be described elegantly in terms of pure spinors on the generalized tangent bundle T+T. This leads to constraints on M6 involving Hitchin's "generalized complex geometry". In this talk, we apply the same techniques to any tendimensional supersymmetric solution, not necessarily factorized as AdS4xM6 or Mink4xM6. I will describe a system of differential equations in terms of forms describing a âgeneralized ISpin(7) structureâ is equivalent to unbroken supersymmetry, in both IIA and IIB. One of the equations in the system reproduces in one fell swoop all the pure spinors equations for fourdimensional vacua.

Solutions of string/M theory with low energy supersymmetry have moduli fields with masses which are generically of order the mass of the gravitino. This leads to a spectrum of superpartners with squarks and sleptons just beyond the LHC energy scale. Gluinos could however be produced at the LHC and decay with top and bottom rich final states. The mass of the lightest Higgs boson is predicted to be between 122 and 129 GeV. The moduli fields dominate the preBBN Universe leading to a nonthermal history which significantly impacts our picture of dark matter, which is predicted to have two components: axions and Wino like WIMPS. The tentative high energy photon signal in the FermiLAT data can be successfully interpreted as the annihilation of these WIMPs into the Zboson and a photon. Moreover, we demonstrate that this signal is also consistent with an approximately 50% axion component. The axion component implies that experiments like Planck will NOT observe tensor modes in the CMB.

Geometry and Connectedness of Heterotic String Compactifications with Fluxes
de la Ossa, X (University of Oxford)
Wednesday 11 January 2012, 10:0011:00
I will discuss the geometry of heterotic string compactifications with fluxes. The compactifications on 6 dimensional manifolds which preserve N=1 supersymmetry in 4 dimensions must be complex conformally balanced manifolds which admit a nowwhere vanishing holomorphic (3,0)form, together with a holomorphic vector bundle on the manifold which must admit a Hermitian YangMills connection. The flux, which can be viewed as a torsion, is the obstruction to the manifold being Kahler. I will describe how these compactifications are connected to the more traditional compactifications on CalabiYau manifolds through geometric transitions like flops and conifold transitions. For instance, one can construct solutions by flopping rational curves in a CalabiYau manifold in such a way that the resulting manifold is no longer Kahler. Time permitting, I will discuss open problems, for example the understanding of the the moduli space of heterotic compactifications and the related problem of determining the massless spectrum in the effective 4 dimensional supersymmetric field theory. The study of these compactifications is interesting on its own right both in string theory, in order to understand more generally the degrees of freedom of these theories, and also in mathematics. For instance, the connectedness between the solutions is related to problems in mathematics like the conjecture by Miles Reid that complex manifolds with trivial canonical bundle are all connected through geometric transitions.

GLSM descriptions of heterotic compactification spaces
Ruehle, F (Universität Bonn)
Thursday 28 June 2012, 16:3016:45
Gauged Linear Sigma Models (GLSMs) provide a framework for studying different phases of compactification spaces for heterotic string theories. Among them are toroidal orbifolds and smooth CalabiYau constructions, both of which are very popular among string model builders. Up to now, quite a few MSSMlike string models have been constructed based on these compactification spaces. We describe the construction of toroidal orbifolds and describe how to obtain their smooth CalabiYau counterparts in the GLSM framework. The two regimes lie at different regions in Kahler moduli space, which can be accessed by tuning the FayetIliopoulos GLSM parameters. However, upon probing the entire moduli space, also other phases are encountered which do not have a geometric interpretation as straightforward as the previously mentioned ones. Furthermore, there can be flop and floplike transitions which further subdivide the different phases.

Gravity duals of supersymmetric gauge theories on curved manifolds
Sparks, J (University of Oxford)
Thursday 22 March 2012, 11:3012:30
It has recently been shown that one can define threedimensional N=2 supersymmetric gauge theories on compact curved manifolds (certain squashed spheres and Lens spaces). Moreover, the expectation value of any BPS operator in such a theory localizes, reducing the path integral to a finite dimensional matrix integral. I will explain how to construct gravity duals to a large class of such theories, which have a large N limit. The gravitational free energy is shown to precisely match the corresponding field theory free energy, as a function of geometric parameters in the large N limit.

Only a few years old, the idea that kinematic building blocks of scattering amplitudes have the same structure and properties as the Liealgebra color factors  known as colorkinematics duality  has proven quite fruitful. Although the origins of the kinematic Liealgebra structure remains unknown, it has improved our understanding of nonplanar gauge theory and gravity. In this talk, I will review the status of colorkinematics duality at tree and loop level, illuminating the open problems as well as the techniques for calculating nonplanar YangMills and gravity loop amplitudes.

We undertake a systematic scan of vector bundles over the database of torically generated CalabiYau threefolds in the context of heterotic string compactifications. Specifically, we construct positive monad bundles over CalabiYau hypersurfaces in toric varieties, with the number of Kahler moduli equal to one, two and three, and extract physically interesting models. We select models which can possibly lead to three families of matter after quotienting by a freelyacting discrete symmetries and including Wilson lines. About 2000 such models on two manifolds are found.

Higher spin gravity in three dimensions is holographically dual to a twodimensional CFT with extended conformal symmetry, known as a Walgebra. This raises the possibility of tackling difficult questions in holography or quantum gravity by exploiting the Walgebra to do exact computations at all values of the coupling. I will review the status of various higher spin dualities, and for the case of AdS_3, describe the detailed matching of the spectrum and the CFT interpretation of higher spin black holes.

We review the construction of supergravity solutions in six dimensional supergravity which are preserve half the super symmetries of the AdS3 x S3 vacuum and give a realization of 2 dimensional interface CFTs of the Janus type. By relaxing the regularity conditions we enlarge the space of solutions to include two new halfBPS configurations, which we refer to as the cap and funnel. We present evidence that solutions which include caps can be used to give a holographic realization of boundary CFTs.

I will summarise the search for candidate dual geometries to 3dimensional Nextended superconformal field theories, with N>4. This includes a classification of elevendimensional homogeneous lorentzian manifolds with a transitive isometric action of SO(3,2) x SO(N). We find no (new) backgrounds with N>5, but several new (to us) backgrounds with N=5, at least one of which is supersymmetric. We consider both AdS and nonAdS backgrounds. This is work in progress with Mara Ungureanu.

We investigate the validity of effective field theory methods and the decoupling of heavy fields during inflation. Considering models of inflation in which the inflaton is coupled to heavy degrees of freedom, we find that violations of decoupling are absent unless there is a breakdown of the slowroll conditions. Next we allow for a temporary departure from inflation resulting in a period of nonadiabaticity during which effective field theory methods are known to fail. We find that the locality of the event and energy conservation lead to a tight bound on the size of the effects of the heavy field.

When approaching a spacelike singularity the BKL conjecture states that the classical relativity dynamics are governed by chaotic oscillations. These can be alternatively described using a socalled cosmological billiard. When quantising this system one is led to automorphic forms of hyperbolic Weyl groups. The construction of some of these automorphic forms can be phrased conveniently using division algebras. If time permits some features of other Eisenstein series will also be discussed.

I will discuss recent work constructing heterotic standard models by compactifying on smooth CalabiYau threefolds in the presence of purely Abelian internal gauge fields. The simple construction of these models allows for a largescale, algorithmic approach to the study of heterotic string vacua. In particular, a systematic search over complete intersection CalabiYau manifolds with less than six Kahler parameters has lead to over 1000 such models with exact Standard Model spectra. In addition, the presence of additional global U(1) symmetries, leads to a rich variety of geometric/phenomenological structures and provides a window into a larger moduli space of nonAbelian vector bundles.

An "axiverse" is a generic prediction of string theory, although the axions are typically extremely hard to detect, and sometimes may not actually solve the strong CP problem. I shall discuss how the axiverse is realised in the LARGE volume scenario, including what the axion couplings are, whether they can be detected, how the QCD axion can arise  and also how to build models with an additional axionlike particle that could explain some intriguing astrophysical anomalies.

I will show how loop space can be used in the description of M5branes. I will focus mainly on the description of selfdual strings as well as a selfdual string analogue of magnetic bags. I will develop a Nahm transform for both cases and construct a number of explicit solutions. I will also show how loop space gives a natural interpretation to a recently proposed set of N=(2,0) supersymmetric equations which might describe M5branes.

The low energy dynamics of M2branes at a CY4 singularity, possibly with torsion flux, is a 3d N=2 superconformal theory. I will describe a type IIA reduction that allows, in some cases, to read off from Dbranes a field theory description, as a ChernSimonsmatter quiver gauge theory with flavors and unequal ranks. I will also discuss how to compute the quantum moduli space of these theories.

The sixdimensional (2,0) M5brane CFT was recently conjectured to be obtainable as the strongcoupling limit of fivedimensional, maximally supersymmetric YangMills theory. In this talk we will first review the arguments leading to this claim. We will then present new evidence in its favour through the study of the M2/M5 bound state, which provides an Mtheoretic realisation of the Myers branepolarisation effect.

String/M theory compactifications with low energy supersymmetry tend to predict that dark matter has two components: axions and WIMPs \cite{1004.5138,1204.2795}. In accord with this, we show that the tentative 130 GeV gammaline signal reported in \cite{1204.2797} can be interpreted as arising from the annihilation of 145 GeV mass, Winolike WIMPs into a Zboson and a photon. In this context, the signal implies a second component of dark matter which we interpret as being composed of axions  the relative Wino/Axion abundances being approximately equal. Further predictions are implied: signals in both diffuse and monochromatic photons from dwarf spheroidal galaxies; monochromatic photons with energy 145 GeV; for the LHC, the Higgs boson mass has been predicted in this framework \cite{1112.1059}, and the current Higgs limits provide interesting constraints on the mass of the Gluino.

M5instanton corrections to the superpotential in fourdimensional Ftheory compactifications have a modulidependent prefactor which contains interesting physical content. In two examples obtained via heterotic duality, I will show that the entire vanishing locus of the prefactor can be understood via simple Ftheory physics, often occurring at enhanced symmetry points in the complex structure moduli space. If time permits, I will discuss the relationship between line bundle cohomology on a distinguished curve in the instanton worldvolume and the intermediate Jacobian of the M5instanton.

I will show how these constructions lead to a nonzero Hflux at next to leading order, and how this flux may be used to stabilise either the dilaton, or the volume of the internal space. I will then add a gaugino condensate to the 4D supergravity, and show that for certain bundle choices it is possible to stabilise all moduli at consistent values.

The degrees of freedom of any interacting quantum field theory are entangled in momentum space. Thus, in the vacuum state, the infrared degrees of freedom are described by a density matrix with an entanglement entropy. We derive a relation between this density matrix and a Wilsonian effective action. We argue that the entanglement entropy of and mutual information between subsets of field theoretic degrees of freedom at different momentum scales are natural observables in quantum field theory and demonstrate how to compute these in perturbation theory. The results may be understood heuristically based on the scaledependence of the coupling strength and number of degrees of freedom. We measure the rate at which entanglement between degrees of freedom declines as their scales separate and suggest that this decay is related to the property of decoupling in quantum field theory.

We study models of multifield inflation in which the inflationary trajectory contains a strong bending occurring when the observable scales are still inside the Hubble radius. We discuss the impact of such a fasttirn feature on the dynamics of the inflationary perturbations  and the traces such an event may leave in the power spectrum of curvature perturbations.

Nflation and Noboundary measure
Kim, SA (Asia Pacific Center for Theoretical Physics)
Tuesday 26 June 2012, 14:3014:45
In this talk, I will give a brief review on Nflation models. Moreover, I will present the recent work of Nflation with noboundary condition which is one of several ways to avoid the singularities of our very early Universe. Even though noboundary measure disfavours the histories of large efoldings in inflation, we show another way to lift up the probability of inflationary histories without considering any other factors, but with the large number of fields such as Nflation fields.

N=8 supergravity is currently at the center of many investigations because of its possible ultraviolet finiteness. I will present some new results on its spontaneously broken version. I will prove that all models with N=0 Minkowski vacua are finite at 1loop. I will also discuss a new mechanism to study the classical vacua, show that there are many more deformations than previously expected and that from a stringy perspective broken N=8 supergravity exhibits a moduli space with some intriguing features.

I will describe recent work on a new class of dualities, directly inherited from IIB Sduality, in 4d theories with 4 supercharges.
I will focus on the microscopic description of the duality, when realized in terms of system of branes at singularities in string theory. The theories in question are obtained by considering, in addition to the fractional branes, orientifold planes wrapping vanishing 4cycles.
I will discuss the system from the point of view of large volume branes, focusing in particular on the relevant issues when continuing orientifolds of quiver gauge theories to large volume. This discussion provides a first principles derivation of the relevant orientifolded quivers. By studying the strongly coupled behavior of the resulting orientifold+brane configuration, I will argue for the existance of a dual, weakly coupled description of the strongly coupled quiver theory at the singularity.

We first review the general features underlying the construction of the 3D New Massive Gravity theory. Next, we show in which sense, at least at the linearized level, this theory can be extended to higher dimensions. An important role is played by exotic representations of massive spin 2. The prospect for interactions is discussed.

I will discuss the realization of nonabelian discrete gauge symmetries in field theory and string theory, and present several classes of string models exhibiting nonabelian discrete gauge symmetries. In models of magnetized/intersecting Dbranes, the discrete symmetries impose nontrivial constraints on Yukawa couplings, and correspond to interesting flavour symmetries in MSSMlike models.

Nongeometric fluxes appear in fourdimensional gauged supergravities through specific terms in the potential. These terms are of phenomenological interest for the matters of moduli stabilization or de Sitter solutions. Unfortunately, their tendimensional origin, and their relation to nongeometry, remain unclear. In this talk, I will present recent progress on these questions. Thanks to a field redefinition in tendimensional supergravity, one makes the nongeometric Q and R fluxes appear, and additionally restores a standard notion of geometry. A dimensional reduction can then be performed, and the fourdimensional nongeometric terms of the scalar potential are recovered.

It has been shown that nongeometric fluxes appear in tendimensional supergravity by performing a field redefinition. Following a similar strategy in double field theory surprisingly allows for a geometric interpretation of these fluxes. More precisely, the Qflux appears as part of a dual curvature scalar, reminiscent of the geometric flux f. The Rflux turns out to be a tensor and appears in the same way as the usual Hflux does. Solving the strong constraint connects this formalism to the tendimensional approach. Furthermore, some recent lifts of fourdimensional gauged supergravity to double field theory can be matched.

I will talk about a recent construction for an action for nonabelian 2form in 6dimensions. The action consists of a nonabelian generalization of the abelian action of Perry and Schwarz for a single M5brane. It admits a selfduality equation on the field strength as the equation of motion. It has a modified 6d Lorentz symmetry. On dimensional reduction on a circle, our action gives the standard 5d YangMills action. Based on these properties, we propose that our theory describes a theory of multiple M5branes in flat space.

Spinorial geometry techniques can be used to classify the nearhorizon geometries of supersymmetric black holes in String/Mtheory. I will illustrate this by presenting the classification of near horizon geometries in IIB supergravity coupled to a nonzero selfdual 5form. The resulting geometries are generically described by a restricted CalabiYau with (hidden) torsion structure. Examples of such solutions will be considered, including a large class of AdS solutions.

Thursday 28 June 2012, 17:4518:00
We examine the conditions for beaming of the gluonic field sourced by a heavy quark in stronglycoupled conformal field theories, using the AdS/CFT correspondence. Previous works have found that, contrary to naive expectations, it is possible to set up collimated beams of gluonic radiation despite the strong coupling. We show that, on the gravity side of the correspondence, this follows directly (for arbitrary quark motion, and independently of any approximations) from the fact that the string dual to the quark remains unexpectedly close to the AdS boundary whenever the quark moves ultrarelativistically. We also work out the validity conditions for a related approximation scheme that proposed to explain the beaming effect though the formation of shock waves in the bulk fields emitted by the string. We find that these conditions are fulfilled in the case of ultrarelativistic uniform circular motion that motivated the proposal, but unfortunately do not hold for much more gen eral quark trajectories.

It has been argued that the generalised KacMoody algebras E11 and E10 encode the symmetries of Mtheory. One may wonder whether a conjecture relating two imperfectly understood constructions can be put to good use. This talk will be a pedagogical introduction to a technique on the KacMoody side that reconstructs wellknown supergravity solutions, albeit smeared down to onedimension. The solutions emerge from a small corner of E11 but the technique may be applied to a much larger sector of E11 and used to propose exotic Mtheory solutions.

If the Higgs boson does not show up soon, we should look for alternative mechanisms of mass generation, satisfying the many experimental constraints which the Standard Model (SM) has successfully fulfilled so far. Following this aim, we present a oneloop calculation of the oblique S parameter within Higgsless models of Electroweak Symmetry Breaking (EWSB) and analyze the phenomenological implications of the available electroweak precision data. By means of an effective Lagrangian we implement the chiral symmetry breaking SU(2)_L x SU(2)_R > SU(2)_(L+R) with Goldstones, gauge bosons and one multiplet of vector and axialvector massive resonance states. Using the dispersive representation of Peskin and Takeuchi and imposing the shortdistance constraints dictated by the operator product expansion, we obtain S at the nexttoleading order in terms of a few resonance parameters. We have found that, in order to match the experimental determination of the S parameter, the res onance masses are required to be over the TeV scale in this kind of stronglycoupled EWSB scenarios.

Open string axions and the flavor problem
Berenstein, D (University of California, Santa Barbara)
Monday 25 June 2012, 11:5512:30
I will describe some bottom up models of particle physics inspired by Dbrane phenomenology that address aspects of the flavor problem. I will argue that many of these models lead to an axion arising from open string modes that sometimes falls within the allowed axion window. The phenomenology of these axion models can rule out many models of physics beyond the standard model. A satisfactory solution of the flavor problem seems to produce models that deconstruct extra dimensions.

I report on a new class of N=1 dualities relating different gauge theories arising from D3 branes probing orientifold singularities. These dualities provide new, nontrivial solutions to the 't Hooft anomaly matching conditions. I discuss an infinite class of orbifold singularities where the duality can be interpreted as Sduality in ten dimensions. I also discuss nonorbifold singularities, and the microscopic interpretation of the duality in terms of an orientifold transition between compact O7+ and O7 planes.

We study the finite temperature theory of padic string models. We analyze the partition function and main thermodynamic properties arising from perturbative thermal loops. We find that the thermal properties of these nonlocal field theories can be interpreted either as contributions of standard thermal modes with energies proportional to the temperature, or inverse thermal modes with energies proportional to the inverse of the temperature, leading to a thermal duality at leading order analogous to the well known Tduality of string theory.

A class of hidden sector polystable vector bundles will be presented that, when used in combination with SU(4) heterotic standard model bundles, lead to completely stable string vacua with exactly the particle spectrum of the MSSM with three righthanded neutrino supermultiplets. Threshold corrections, the effective Lagrangian with soft supersymmetry breaking and its scaling under the renormalization group are discussed. It is shown that gauged BL symmetry and electroweak symmetry are radiatively broken with a small hierarchy over a wide range of initial parameters. Implications of these SU(4) heterotic standard models for the LHC are explored.

We shall detail points of interest for string model builders coming from recent data, providing some targets that model builders may like to hit. In particular, we shall discuss higgs and supersymmetry searches, and infer some general statements about the spectra and naturalness of models. We shall also mention the t tbar asymmetry from the Tevatron, which disagrees with Standard Model expectations, recent relevant B decay results, Daya bay implications for neutrino masses and mixings and an inferred 130 GeV line in gamma rays coming from our galaxy.

Also I will outline some more recent results on similar calculations for closed string moduli.

Quasi Poisson structures, Courant algebroids and Bianchi identities for nongeometric fluxes
Deser, A (MaxPlanckInstitut für Physik, München)
Wednesday 27 June 2012, 16:3016:45
The notion of nongeometric flux was introduced in string theory to correctly describe the degrees of freedom in fourdimensional effective superpotentials of type II flux compactifications. Whereas the Hflux is simply the field strength of the NSNS Bfield and the fflux can be interpreted as the structure constants of a nonholonomic basis of the tangent bundle, the physical and mathematical properties of the remaining Q and Rfluxes are to a great extent unknown. In this talk, we will first use the notion of a (quasi)Poisson structure to rederive directly on the tangent bundle the commutation relations containing all four fluxes as structure constants. As a consequence, we get Bianchitype identities for the fluxes by writing down the Jacobiidentities for the algebra. Using these Bianchiidentities and the theory of quasi Liealgebroids, we are able to identify the associated Courant algebroid structure, which is essential for dealing with all fluxes being nonzero.

We will discuss reductions of Mtheory and type II theories to four dimensions preserving N=1 and N=2 supersymmetry, in the language of exceptional generalized geometry. We will introduce the relevant structures which encode the NSNS and RR degrees of freedom, discuss the geometry of their orbits under the action of the Uduality group (i.e., the moduli space metrics), and how they enter in the superpotential.

Moduli stabilization in the Large Volume Scenario requires a specific kind of sixdimensional CalabiYau geometry for the compactification procedure, which is being referred to as "Swiss Cheese" due to the presence of certain holes for instanton wrappings. Only a handful of such manifolds are known explicitly. I will give an overview of the Large Volume Scenario and present recent progress on a general scan of the CalabiYau threefold landscape for the Swiss Cheese property.

A great deal of progress has been made in computing scattering amplitudes in 4d quantum field theories by expressing the amplitudes in terms of variables known as twistors. In this talk, I will describe twistorial methods for computing scattering amplitudes in 3d quantum field theories, in particular superconformal ChernSimons theories and supersymmetric YangMills theories. These methods have led to the discovery of new symmetries and dualities in 3d quantum field theories.

We study pure SeibergWitten theories with SU(r+1) and Sp(2r) gauge groups with no flavors. We study singularity loci of moduli space of the SeibergWitten curve. Using exterior derivative and discriminant operators, we can find ArgyresDouglas loci of the SW theory. We also compute BPS charges of the massless dyons of SU and Sp SW theory. In a detailed example of C_2=Sp(4), we find 6 points in the moduli space where we have 2 massless BPS dyons, and 3 of them give ArgyresDouglas loci. We show that BPS charges of the massless dyons jump as we go across ArgyresDouglas loci, giving an explicit example of ArgyresDouglas loci living inside the wall of marginal stability.

We shall compare these solition star solutions with other existing zero temperature solutions and find interesting phase transitions in certain regions of parameter space. We will also analyze the probe fermion equations (in the WKB approximation) in the background of this soliton star geometry to confirm the presence of many sharp Fermisurfaces in the system.

Spontaneous Partial Supersymmetry Breaking
Smyth, P (EPFL  Ecoles Polytechniques Fédérales de Lausanne)
Tuesday 26 June 2012, 14:3014:45
I will review some recent work on spontaneous partial supersymmetry breaking in extended supersymmetry. I will first describe the nogo theorems which forbid N=2 to N=1 spontaneous supersymmetry breaking in global and local supersymmetry, before showing how they are circumvented. I will then discuss some new techniques involving the embedding tensor formalism which allow us to study this problem systemically and find the lowenergy effective theory in the N=1 vacuum. This leads to interesting insights into spontaneous partial supersymmetry breaking in supergravity and string theory, as well as new results in quaternionic geometry.

In some occasions, certain finite groups display a close connection to certain modular objects defined on the upperhalf plane. The most wellknown of such a relation between these two distinct mathematical structures is the socalled monstrous moonshine, relating the largest sporadic group to a set of modular functions. String theory, with its power to geometrise automorphic objects, has been proven instrumental in providing insights into these mysterious relations. Recently, certain unexpected relation with various similarities to the monstrous moonshine has been discovered. In this talk I will review these recent mathematical developments, while putting extra focus on the role played by string theory.

String theory is at the cutting edge of theoretical physics. Its deep goal is to unify the conflicting paradigms of quantum mechanics and relativity. In doing so, string theory brings up new ways of seeing the world, with hidden dimensions and novel surprising symmetries and relationships. This event will begin with an accessible introduction to string theory by David Berman followed by a presentation and discussion with Grenville Davey on his art and how aspects of string theory and contemporary physics have been an inspiration.

Extra U(1) extensions of the Standard Model arising from string theory have been considered in the literature since the mid80s. Such a U(1) can play an important phenomenological role in solving the \mu problem and suppressing other unwanted operators, such as dimension four and five proton decay mediating operators. Yet keeping the U(1) unbroken down to low scales in quasirealistic string models turns out to be highly nontrivial. In this talk I will discuss the constraints and some scenarios in which they may be alleviated.

We consider closed bosonic string theory with flat background and constant Hflux. Up to linear order in the flux, this is a solution to the string equations of motion and we are able to define a worldsheet conformal field theory framework to compute scattering amplitudes. In the easiest cases of npoint tachyon amplitudes, we use the properties of the Rogers dilogarithm function to speculate about the nature of the product of functions on spacetimes Tdual to the original configuration.

Thursday 28 June 2012, 16:1516:30
It is wellknown that the beta functions on a string worldsheet correspond to the target space equations of motion, e.g. the Einstein equations. We show that the BPS equations, i.e. the conditions of vanishing supersymmetry variations of the spacetime fermions, can be directly derived from the worldsheet. To this end we consider a heterotic worldsheet model in the RNSformulation with (2,0) supersymmetry, which describes a complex torsion target space that supports a holomorphic vector bundle. After a detailed account of its quantization and renormalization, we establish that super Weyl anomaly cancellation implies the heterotic BPS conditions: At the one loop level the geometry is required to be conformally balanced and the gauge background has to satisfy the Hermitean YangMills equations.

We show how extensions of conventional differential geometry, so called "generalised geometry", give a natural way of formulating type II and elevendimensional supergravity theories, unifying the bosonic fields and symmetries. There is a natural action of the U and Tduality groups E_d(d) and O(d,d) and the formalism shows that the supergravity theories have an enhanced local symmetry. By introducing the analogue of the LeviCivita connection we find that the action and equations of motion simplify, writable in terms of a generalised Ricci tensor. The connection also encodes the supersymmetry variations and fermionic equations of motion. There are interesting implications for describing supersymmetric backgrounds and connections to the embedding tensor formalism.

Nonperturbative effects such as gaugino condensation on a stack of D7branes are an essential ingredient in several celebrated modulistabilisation schemes in type IIB string theory. At the level of the fourdimensional effective theory, the nonperturbative effects induce a nonperturbative superpotential. In particular, new Yukawa interactions can be generated. Type IIB orbifold models contain the essential features to study these nonperturbative corrections to the superpotential in string compactifications. I will describe under which conditions new Yukawa couplings arise in these settings and generalise the results to more realistic string models. Most importantly, I will show that the flavour structure of the induced Yukawa couplings is not aligned with the treelevel flavour structure, thus introducing a new source of flavor violation.

Thursday 16 February 2012, 11:3012:15
This talk aims to illustrate our recent supersymmetric extension of double field theory and its connection to supergravity. In terms of novel stringy differential geometry we propose, our action consists of five simple terms  two bosonic plus three fermionic  and manifests not only diffeomorphism and oneform gauge symmetry of Bfield, but also O(10,10) Tduality as well as a direct product of two local Lorentz symmetries, SO(1,9) times SO(9,1). A gauge fixing that identifies the double local Lorentz groups reduces our action to the N=1 supergravity in ten dimensions.

After reviewing some virtues and problems of the minimal supersymmetric standard model (MSSM), I will show that, if one demands anomaly freedom and fermion masses, only R symmetries can forbid the supersymmetric Higgs mass term mu. I will then prove that R symmetries are not available in conventional grand unified theories (GUTs) and argue that this prevents natural solutions to the doublettriplet splitting problem in four dimensions. On the other hand, higherdimensional GUTs do not suffer from this problem. I will briefly discuss an explicit stringderived model in which the mu and dimension five proton decay problems are solved by an order four discrete R symmetry, and comment on the higherdimensional origin of this symmetry.

I shall talk about a class eight derivative interactions in the effective action of type IIB string theory compactified on T^2. These 1/2 BPS interactions have moduli dependent couplings. I shall impose the constraints of supersymmetry to show that each of these couplings satisfy a first order differential equation on moduli space which relate it to other couplings in the same supermuliplet. The couplings which only depend on the SO(2)\SL(2,R) moduli satisfy Laplace equation on moduli space. On the other hand, the ones which only depend on the SO(3)\SL(3,R) moduli are far more complicated, and satisfy Poisson equation on moduli space, where the source terms are given by other couplings in the same supermultiplet.

I will describe the application of a bootstrap program for scattering amplitudes based on analytic constraints from the operator product expansion for lightlike Wilson loops and multiRegge limits. Together with an ansatz for the space of relevant functions these place powerful constraints on the form of multiloop amplitudes.

Systematic Investigations of the Heterotic String Landscape
Cleaver, G (Baylor University)
Wednesday 27 June 2012, 17:1517:30
Results are reviewed for the first stages of Baylor University’s ongoing systematic statistics investigations of the parameter space of free fermionic heterotic string models. Presented is the complete set of D = 4, 6 models with either maximal or completely broken spacetime SUSY that are constructed from the untwisted sector and exactly one additional gauge sector containing anywhere from order 2 through 32 twists. All additional models generated to date with additional twisted gauge sectors are also discussed. A vast degeneracy among models appears: from the roughly 2 billion D = 4 models with a single twist sector, only 577 physically distinct models appear. 68 of these have N = 4 SUSY and 509 have completely broken SUSY. To date, no new physically distinct models appear among any of those formed from two or more twisted gauge sectors. Several redundancies among D= 4 models and among D= 6 models are proven to result from redundancies already present among D= 10 models . Methods to reduce redundancies in D= 4, 6 systematic searches are summarized. Statistics regarding the appearance of various combinations of gauge group factors and of GUT groups among the set of 577 physically unique models are presented. Lastly, moving briefly to models with matter sectors, a model with an even number D of large spacetime dimensions is shown to always have maximal SUSY, if it is formed from the untwisted sector and a sector with a massless leftmover and an odd ordered rightmover.

We attempt an estimate for the distribution of the tensor mode fraction r over the landscape of vacua in string theory. The dynamics of eternal inflation and quantum tunneling lead to a kind of democracy on the landscape, providing no bias towards largefield or smallfield inflation regardless of the class of measure. The tensor mode fraction then follows the number frequency distributions of inflationary mechanisms of string theory over the landscape. We show that an estimate of the relative number frequencies for smallfield vs largefield inflation, while unattainable on the whole landscape, may be within reach as a regional answer for warped CalabiYau flux compactifications of type IIB string theory.

In this talk we review the known higherderivative couplings in supergravity with eight supercharges in 4 and 5 spacetime dimensions. These couplings play an important role in deriving the subleading corrections to BPS black hole entropy. It is demonstrated how an offshell 4D/5D connection clarifies previous results and leads to new insights.

We discuss holographic superconductivity in the context of IIB on AdS_5 x T^{1,1}. In the spectrum on the gravity side, there are several modes with potential instabilities. In addition to the one identifed by Gubser et al, we point out that there is another, potentially more unstable mode. Moreover, we propose a concrete model for the dynamics of this mode. With this proposal at hand, we show that it indeed dominates the thermodynamics at low temperatures.

I will discuss the mass spectrum of fourdimensional {\cal N}=1 supergravity in which the Kähler potential and superpotential are taken to be random functions of N chiral superfields. For both supersymmetric and nonsupersymmetric critical points, the ensemble of Hessian matrices can be efficiently studied through the ‘Coulomb gas’ formulation of Random Matrix Theory. At large N, the supersymmetric AdS vacua have a very peculiar spectrum which typically includes many BFallowed tachyons, and I will briefly discuss the prospects of obtaining metastable de Sitter vacua from an ‘uplift’ of a supersymmetric AdS vacuum. An exponentially small fraction de Sitter critical points with spontaneously broken supersymmetry are metastable vacua, and I will discuss how the Coulomb gas formulation can be used to find the joint probability distribution of the masses, the fraction of critical points which are vacua, and the spectrum of the vacua. I will conclude by b riefly discussing some cosmological consequences of these results.

We show that in a general N=1 supergravity with N >> 1 scalar fields, an exponentially small fraction of the de Sitter critical points are metastable vacua. Taking the superpotential and Kahler potential to be random functions, we construct a random matrix model for the Hessian matrix, which is wellapproximated by the sum of a Wigner matrix and two Wishart matrices. We compute the eigenvalue spectrum analytically from the free convolution of the constituent spectra and find that in typical configurations, a significant fraction of the eigenvalues are negative. Using Coulomb gas techniques, we then determine the probability P of a large fluctuation in which all the eigenvalues become positive. Strong eigenvalue repulsion makes this extremely unlikely: we find P \propto exp(c N^2), with c a constant, for generic critical points. Our results have significant implications for the counting of de Sitter vacua in string theory, but the number of vacua remains vast.

The location of particles in extra dimensions determines the properties of the 4dimensional lowenergy effective action, such as Yukawa couplings and the pattern of supersymmetry breakdown. We analyze these questions in the framework of the heterotic MiniLandscape.

Dbrane worlds have provided a geometrically intuitive approach for Standard Model (SM) engineering within string theory compactifications. While the types and ranks of gauge groups and the chiral matter content are tackled in a straightforward manner, it remains on the one hand an open question if the SM can be obtained on rigid Dbranes  without continuous gauge symmetry breaking along flat directions and with nontrivial Dbrane instanton contributions to the effective action  and on the other hand if such models are consistent with lowenergy data. The T6/Z(2)xZ(6') orbifold with discrete torsion admits a plethora of leftright symmetric `local models' without exotic matter in the adjoint, symmetric or antisymmetric representation. However, `global' completions usually come at the cost of introducing new exotic states in bifundamental representations. It furthermore turns out that USp(2) and SO(2) in place of U(2) symmetries can at most provide one particle generation. Last but not least, it turns out that for any T6/Z(2)xZ(2M) orbifold with discrete torsion and tilted tori, orientifold invariant stacks of D6branes carry USp(2N) or SO(2N) gauge groups depending on their relative position to the exotic O6plane. The new classification reduces the number of Ktheory constraints. If time permits, I will briefly comment on the drastic change in the pattern of Yukawa couplings on orbifolds compared to the sixtorus using a T6/Z6' example. As a result, quark Yukawas can provide large mixings while lepton Yukawas are flavour diagonal at leading order. Also the rule of `one massive generation only' is circumvented.
