On sgoldstino-less supergravity models of inflation

Gianguido Dall'Agata, Fabio Zwirner

We go a step further in the search for a consistent and realistic supergravity model of large-field inflation by building a class of models with the following features: during slow…

On the Subleading-Soft Behaviour of QCD Amplitudes

Hui Luo, Pierpaolo Mastrolia, William J. Torres Bobadilla

We elaborate on the radiative behaviour of tree-level scattering amplitudes in the soft regime. We show that the sub-leading soft term in single-gluon emission of quark-gluon ampli…

Warping the Kähler potential of F-theory/IIB flux compactifications

Luca Martucci

We identify the low-energy Kähler potential of warped F-theory/IIB flux compactifications whose light spectrum includes universal, Kähler, axionic and mobile D3-brane moduli. The d…

Uplifting non-compact gauged supergravities

Walter H. Baron, Gianguido Dall'Agata

We provide the M-theory uplift of de Sitter vacua of SO(5,3) and SO(4,4) gaugings of maximal supergravity in 4 dimensions. We find new non-compact backgrounds that are squashed hyp…

The Challenge of Realizing F-term Axion Monodromy Inflation in String Theory

Ralph Blumenhagen, Daniela Herschmann, Erik Plauschinn

A systematic analysis of possibilities for realizing single-field F-term axion monodromy inflation via the flux-induced superpotential in type IIB string theory is performed. In th…

Mass-deformed Brane Tilings

Massimo Bianchi, Stefano Cremonesi, Amihay Hanany +3

We study renormalization group flows among N=1 SCFTs realized on the worldvolume of D3-branes probing toric Calabi-Yau singularities, thus admitting a brane tiling description. The…

Higher Spins in Hyper-Superspace

Ioannis Florakis, Dmitri Sorokin, Mirian Tsulaia

We extend the results of arXiv:1401.1645 on the generalized conformal Sp(2n)-structure of infinite multiplets of higher spin fields, formulated in spaces with extra tensorial direc…

On T-duality transformations for the three-sphere

Erik Plauschinn

We study collective T-duality transformations along one, two and three directions of isometry for the three-sphere with H-flux. Our aim is to obtain new non-geometric backgrounds a…

Gauge and matter superfield theories on

I. B. Samsonov, D. Sorokin

We develop a superfield formulation of gauge and matter field theories on a two-dimensional sphere with rigid N=(2,2) as well as extended supersymmetry. The construction is based o…

Modular anomaly equations in N=2* theories and their large-N limit

M. Billo, M. Frau, F. Fucito +4

We propose a modular anomaly equation for the prepotential of the N=2* super Yang-Mills theory on R^4 with gauge group U(N) in the presence of an Omega-background. We then study th…

Superconformal structures on the three-sphere

Sergei M. Kuzenko, D. Sorokin

With the motivation to develop superconformal field theory on S^3, we introduce a 2n-extended supersphere S^{3|4n}, with n=1,2,..., as a homogeneous space of the three-dimensional…

Entanglement Entropy and D1-D5 geometries

Stefano Giusto, Rodolfo Russo

In Conformal Field Theories with a gravitational AdS dual it is possible to calculate the entanglement entropy of a region holographically by using the Ryu-Takayanagi formula.…

Electrodynamics of massless charged particles

Kurt Lechner

We derive the classical dynamics of massless charged particles in a rigorous way from first principles. Since due to ultraviolet divergences this dynamics does not follow from an a…

Symmetries, Sum Rules and Constraints on Effective Field Theories

Brando Bellazzini, Luca Martucci, Riccardo Torre

Using unitarity, analyticity and crossing symmetry, we derive universal sum rules for scattering amplitudes in theories invariant under an arbitrary symmetry group. The sum rules r…

Symplectic Deformations of Gauged Maximal Supergravity

Gianguido Dall'Agata, Gianluca Inverso, Alessio Marrani

We identify the space of symplectic deformations of maximal gauged supergravity theories. Coordinates of such space parametrize inequivalent supergravity models with the same gauge…

Gaugings from E7 Extended Geometries

Walter H. Baron

We discuss the construction of gaugings in recent models of E7 Extended Geometries, focusing on the two inequivalent SL(8) truncations of the theory. In these sectors the condition…

Towards Universal Axion Inflation and Reheating in String Theory

Ralph Blumenhagen, Erik Plauschinn

The recent BICEP2 measurements of B-modes indicate a large tensor-to-scalar ratio in inflationary cosmology, which points towards trans-Planckian evolution of the inflaton. We prop…

Geometrical hierarchies in classical supergravity

Hui Luo, Fabio Zwirner

We introduce a supergravity model with a very simple hidden sector coupled to the electroweak gauge and Higgs sectors of the MSSM. At the classical level, supersymmetry and $…

Topological duality twist and brane instantons in F-theory

Luca Martucci

A variant of the topological twist, involving SL(2,Z) dualities and hence named topological duality twist, is introduced and explicitly applied to describe a U(1) N=4 super Yang-Mi…
