Inflatino-less Cosmology

John Joseph M. Carrasco, Renata Kallosh, Andrei Linde

We construct inflationary models in the context of supergravity with orthogonal nilpotent superfields [1]. When local supersymmetry is gauge-fixed in the unitary gauge, these model…

Proof of a modular relation between 1-, 2- and 3-loop Feynman diagrams on a torus

Eric D'Hoker, Michael B. Green, Pierre Vanhove

The coefficients of the higher-derivative terms in the low energy expansion of genus-one graviton Type II superstring scattering amplitudes are determined by integrating sums of no…

D3-brane model building and the supertrace rule

Iosif Bena, Mariana Graña, Stanislav Kuperstein +2

A common way to obtain standard-model-like Lagrangians in string theory is to place D3-branes inside flux compactifications. The bosonic and fermionic masses and couplings of the r…

formalism from superpotential and holography

Jaume Garriga, Yuko Urakawa, Filippo Vernizzi

We consider the superpotential formalism to describe the evolution of scalar fields during inflation, generalizing it to include the case with non-canonical kinetic terms. We provi…

Quantum Gravity Constraints from Unitarity and Analyticity

Brando Bellazzini, Clifford Cheung, Grant N. Remmen

We derive rigorous bounds on corrections to Einstein gravity using unitarity and analyticity of graviton scattering amplitudes. In spacetime dimensions, these consistency…

Holographic description of non-supersymmetric orbifolded D1-D5-P solutions

Bidisha Chakrabarty, David Turton, Amitabh Virmani

Non-supersymmetric black hole microstates are of great interest in the context of the black hole information paradox. We identify the holographic description of the general class o…

Dynamics of Perturbations in Double Field Theory & Non-Relativistic String Theory

Sung Moon Ko, Charles Melby-Thompson, Rene Meyer +1

Double Field Theory provides a geometric framework capable of describing string theory backgrounds that cannot be understood purely in terms of Riemannian geometry -- not only glob…

The M-theory origin of global properties of gauge theories

Antonio Amariti, Claudius Klare, Domenico Orlando +1

We show that global properties of gauge groups can be understood as geometric properties in M-theory. Different wrappings of a system of N M5-branes on a torus reduce to four-dimen…

Bootstrapping correlation functions in N=4 SYM

Dmitry Chicherin, Reza Doobary, Burkhard Eden +3

We describe a new approach to computing the chiral part of correlation functions of stress-tensor supermultiplets in N=4 SYM that relies on symmetries, analytic properties and the…

New gaugings and non-geometry

Kanghoon Lee, Charles Strickland-Constable, Daniel Waldram

We discuss the possible realisation in string/M theory of the recently discovered family of four-dimensional maximal gauged supergravities, and of an analogous family of se…

F-theory at order

Ruben Minasian, Tom G. Pugh, Raffaele Savelli

We study the effective physics of F-theory at order in derivative expansion. We show that the ten-dimensional type IIB eight-derivative couplings involving the graviton and…

The Equivalence Principle in a Quantum World

N. E. J. Bjerrum-Bohr, John F. Donoghue, Basem Kamal El-Menoufi +3

We show how modern methods can be applied to quantum gravity at low energy. We test how quantum corrections challenge the classical framework behind the Equivalence Principle, for…

Universal dS vacua in STU-models

J. Blåbäck, U. H. Danielsson, G. Dibitetto +1

Stable de Sitter solutions in minimal F-term supergravity are known to lie close to Minkowski critical points. We consider a class of STU-models arising from type IIB compactificat…

Weakly Broken Galileon Symmetry

David Pirtskhalava, Luca Santoni, Enrico Trincherini +1

Effective theories of a scalar invariant under the internal \textit{galileon symmetry} have been extensively studied due to their special theoretical and phenome…

4D/3D reduction of dualities: mirrors on the circle

Antonio Amariti, Davide Forcella, Claudius Klare +2

We engineer a brane picture for the reduction of Seiberg dualities from 4D to 3D, valid also in the presence of orientifold planes. We obtain effective 3D dualities on the circle b…

Cuts and coproducts of massive triangle diagrams

Samuel Abreu, Ruth Britto, Hanna Grönqvist

Relations between multiple unitarity cuts and coproducts of Feynman integrals are extended to allow for internal masses. These masses introduce new branch cuts, whose discontinuiti…

Habemus Superstratum! A constructive proof of the existence of superstrata

Iosif Bena, Stefano Giusto, Rodolfo Russo +2

We construct the first example of a superstratum: a class of smooth horizonless supergravity solutions that are parameterized by arbitrary continuous functions of (at least) two va…

Liouville theory with a central charge less than one

Sylvain Ribault, Raoul Santachiara

We determine the spectrum and correlation functions of Liouville theory with a central charge less than (or equal) one. This completes the definition of Liouville theory for all co…

Linking loops in ABJM and refined theory

Taro Kimura

We consider the link average of the half-BPS Wilson loop operators in N = 6 superconformal Chern-Simons-matter theory, which is called ABJM theory. We show that this loop average i…

M-theory on non-Kähler manifolds

C. S. Shahbazi

We show that supersymmetric M-theory compactifications to three-dimensional Minkowski space-time preserving supersymmetry allow for a class of internal manifolds mo…

On the modular structure of the genus-one Type II superstring low energy expansion

Eric D'Hoker, Michael B. Green, Pierre Vanhove

The analytic contribution to the low energy expansion of Type II string amplitudes at genus-one is a power series in space-time derivatives with coefficients that are determined by…

AdS5 solutions from M5-branes on Riemann surface and D6-branes sources

Ibrahima Bah

We describe the gravity duals of four-dimensional N=1 superconformal field theories obtained by wrapping M5-branes on a punctured Riemann surface. The internal geometry, normal to…
