On p-form gauge theories and their conformal limits

Igor Bandos, Kurt Lechner, Dmitri Sorokin +1

Relations between the various formulations of nonlinear p-form electrodynamics with conformal-invariant weak-field and strong-field limits are clarified, with a focus on duality in…

Weak gravity versus de Sitter

N. Cribiori, G. Dall'Agata, F. Farakos

We show that one can uncover a Dine-Seiberg problem for de Sitter critical points in supergravity theories by utilizing the magnetic weak gravity conjecture. We present a large var…

$N = 2$ consistent truncations from wrapped M5-branes

Davide Cassani, Gregoire Josse, Michela Petrini +1

We discuss consistent truncations of eleven-dimensional supergravity on a six-dimensional manifold $M$ , preserving minimal $N = 2$ supersymmetry in five dimensions. These a…

AdS $_{3}$ from M-branes at conical singularities

Giuseppe Dibitetto, Nicolò Petri

M-theory is known to possess supersymmetric solutions where the geometry is $AdS_{3} \times S^{3} \times S^{3}$ warped over a Riemann surface $Σ_{2}$ . The simplest examples in thi…

Automorphic Forms and Fermion Masses

Gui-Jun Ding, Ferruccio Feruglio, Xiang-Gan Liu

We extend the framework of modular invariant supersymmetric theories to encompass invariance under more general discrete groups $Γ$ , that allow the presence of several moduli and m…

Comments on chiral algebras and $Ω$ -deformations

Nikolay Bobev, Pieter Bomans, Fridrik Freyr Gautason

Every six-dimensional $N = (2, 0)$ SCFT on $R^{6}$ contains a set of protected operators whose correlation functions are controlled by a two-dimensional chiral algebr…

Fun with $F_{24}$

Sarah M. Harrison, Natalie M. Paquette, Daniel Persson +1

We study some special features of $F_{24}$ , the holomorphic $c = 12$ superconformal field theory (SCFT) given by 24 chiral free fermions. We construct eight different Lie superalgebr…

BPS Black Hole Entropy and Attractors in Very Special Geometry. Cubic Forms, Gradient Maps and their Inversion

Bert van Geemen, Alessio Marrani, Francesco Russo

We consider Bekenstein-Hawking entropy and attractors in extremal BPS black holes of $N = 2$ , $D = 4$ ungauged supergravity obtained as reduction of minimal, matter-coupled $…

de Sitter decay through goldstino evaporation

Fotis Farakos, Alex Kehagias, Nikolaos Liatsos

We study supergravity theories with supersymmetry intrinsically non-linearly realized supported only by four-form flux. We demonstrate that supersymmetry can be restored by the eva…

Vertex operator superalgebra/sigma model correspondences: The four-torus case

Vassilis Anagiannis, Miranda C. N. Cheng, John Duncan +1

We propose a correspondence between vertex operator superalgebras and families of sigma models in which the two structures are related by symmetry properties and a certain reflecti…

S matrix for a three-parameter integrable deformation of $A d S_{3} \times S^{3}$ strings

Marco Bocconcello, Isari Masuda, Fiona K. Seibold +1

We consider the three-parameter integrable deformation of the $A d S_{3} \times S^{3}$ superstring background constructed in arXiv:1811.00453. Working on the string worldsheet in uniform…

Bound State Scattering Simplified

Marius de Leeuw, Burkhard Eden, Alessandro Sfondrini

In the description of the AdS5/CFT4 duality by an integrable system the scattering matrix for bound states plays a crucial role: it was initially constructed for the evaluation of…

Decomposition of Feynman Integrals by Multivariate Intersection Numbers

Hjalte Frellesvig, Federico Gasparotto, Stefano Laporta +4

We present a detailed description of the recent idea for a direct decomposition of Feynman integrals onto a basis of master integrals by projections, as well as a direct derivation…

The Regge limit of AdS $_{3}$ holographic correlators

Stefano Giusto, Marcel R. R. Hughes, Rodolfo Russo

We study the Regge limit of 4-point AdS $_{3} \times S^{3}$ correlators in the tree-level supergravity approximation and provide various explicit checks of the relation between the eiko…

Out of the Swampland with Multifield Quintessence?

Michele Cicoli, Giuseppe Dibitetto, Francisco G. Pedro

Multifield models with a curved field space have already been shown to be able to provide viable quintessence models for steep potentials that satisfy swampland bounds. The simples…

A non-linear duality-invariant conformal extension of Maxwell's equations

Igor Bandos, Kurt Lechner, Dmitri Sorokin +1

All nonlinear extensions of the source-free Maxwell equations preserving both SO(2) electromagnetic duality invariance and conformal invariance are found, and shown to be limits of…

Reconsidering the Ostrogradsky theorem: Higher-derivatives Lagrangians, Ghosts and Degeneracy

Alexander Ganz, Karim Noui

We review the fate of the Ostrogradsky ghost in higher-order theories. We start by recalling the original Ostrogradsky theorem and illustrate, in the context of classical mechanics…

Swampland Conjectures for Strings and Membranes

Stefano Lanza, Fernando Marchesano, Luca Martucci +1

Swampland criteria like the Weak Gravity Conjecture should not only apply to particles, but also to other lower-codimension charged objects in 4d EFTs like strings and membranes. H…

The Geometrical Origin of Dark Energy

Alon E. Faraggi, Marco Matone

The geometrical formulation of the quantum Hamilton-Jacobi theory shows that the quantum potential is never trivial, so that it plays the rôle of intrinsic energy. Such a key prope…

The large- $N$ limit of the 4d $N = 1$ superconformal index

Alejandro Cabo-Bizet, Davide Cassani, Dario Martelli +1

We systematically analyze the large- $N$ limit of the superconformal index of $N = 1$ superconformal theories having a quiver description. The index of these theories is kno…

The CFT $_{6}$ origin of all tree-level 4-point correlators in AdS $_{3} \times S^{3}$

Stefano Giusto, Rodolfo Russo, Alexander Tyukov +1

We provide strong evidence that all tree-level 4-point holographic correlators in AdS $_{3} \times S^{3}$ are constrained by a hidden 6D conformal symmetry. This property has been disco…

Spontaneously Broken 3d Hietarinta/Maxwell Chern-Simons Theory and Minimal Massive Gravity

Dmitry Chernyavsky, Nihat Sadik Deger, Dmitri Sorokin

We show that minimal massive 3d gravity (MMG), as well as the topological massive gravity, are particular cases of a more general `minimal massive gravity' theory (with a single ma…
