Axion Landscape Cosmology

Thomas C. Bachlechner, Kate Eckerle, Oliver Janssen +1

We study the cosmology of complex multi-axion theories. With O(100) fields and GUT scale energies these theories contain a vast number of vacua, inflationary trajectories and a nat…

On the supersymmetry invariance of flat supergravity with boundary

Patrick Concha, Lucrezia Ravera, Evelyn Rodríguez

The supersymmetry invariance of flat supergravity (i.e., supergravity in the absence of any internal scale in the Lagrangian) in four dimensions on a manifold with non-trivial boun…

$U S p (2 N_{c})$ SQCD $_{3}$ with antisymmetric: dualities and symmetry enhancements

Antonio Amariti, Luca Cassia

We study various aspects of the 4d/3d reduction of $N = 1$ dualities involving $U S p (2 N_{c})$ gauge theories with $2 N_{f}$ fundamentals and one antisymmetric. We discuss the non…

SUSY Breaking in Monopole Quivers

Antonio Amariti

We claim that 3d monopole quivers, theories with product gauge groups interacting through Affleck-Harvey-Witten superpotentials, are a natural setup for the study of spontaneous br…

Beyond the near-horizon limit: Stringy corrections to Heterotic Black Holes

Pablo A. Cano, Samuele Chimento, Patrick Meessen +3

We study the first-order in $α^{'}$ corrections to 4-charge black holes (with the Reissner-Nordström black hole as a particular example) beyond the near-horizon limit in the Heterotic…

Spinorial geometry, off-shell Killing spinor identities and higher derivative 5D supergravities

Federico Bonetti, Dietmar Klemm, Wafic A. Sabra +1

Killing spinor identities relate components of equations of motion to each other for supersymmetric backgrounds. The only input required is the field content and the supersymmetry…

Generalized cosmological term in D=4 supergravity from a new AdS-Lorentz superalgebra

Diego M. Peñafiel, Lucrezia Ravera

A new supersymmetrization of the so-called AdS-Lorentz algebra is presented. It involves two fermionic generators and is obtained by performing an abelian semigroup expansion of th…

AdS $_{3}$ solutions with exceptional supersymmetry

Giuseppe Dibitetto, Gabriele Lo Monaco, Achilleas Passias +2

Among the possible superalgebras that contain the AdS $_{3}$ isometries, two interesting possibilities are the exceptional $F (4)$ and $G (3)$ . Their R-symmetry is respectively SO(7) an…

1-loop Amplitudes from the Halohedron

Giulio Salvatori

We recently proposed the Halohedron to be the 1-loop Amplituhedron for planar $ϕ^{3}$ theory. Here we prove this claim by showing how it is possible to extract the integrand for the…

New 3d $N = 2$ Dualities from Quadratic Monopoles

Antonio Amariti, Ivan Garozzo, Noppadol Mekareeya

Aspects of three dimensional $N = 2$ gauge theories with monopole superpotentials and their dualities are investigated. The moduli spaces of a number of such theories are s…

Volume and complexity for warped AdS black holes

Roberto Auzzi, Stefano Baiguera, Giuseppe Nardelli

We study the Complexity=Volume conjecture for Warped AdS $_{3}$ black holes. We compute the spatial volume of the Einstein-Rosen bridge and we find that its growth rate is proportiona…

On a family of $α^{'}$ -corrected solutions of the Heterotic Superstring effective action

Samuele Chimento, Patrick Meessen, Tomas Ortin +2

We compute explicitly the first-order in $α^{'}$ corrections to a family of solutions of the Heterotic Superstring effective action that describes fundamental strings with momentum al…

Ultraviolet phenomena in AdS self-interacting quantum field theory

Emil T. Akhmedov, Ugo Moschella, Fedor K. Popov

We study the one-loop corrections to the four-point function in the Anti de Sitter space-time for a $ϕ^{4}$ field theory. Our calculation shows the existence of non-local counterterm…

Hyperbolic Geometry and Amplituhedra in 1+2 dimensions

Giulio Salvatori, Sergio Cacciatori

Recently, the existence of an Amplituhedron for tree level amplitudes in the bi-adjoint scalar field theory has been proved by Arkhani-Hamed et al. We argue that hyperbolic geometr…

Generalized AdS-Lorentz deformed supergravity on a manifold with boundary

A. Banaudi, L. Ravera

The purpose of this paper is to explore the supersymmetry invariance of a particular supergravity theory, which we refer to as D=4 generalized AdS-Lorentz deformed supergravity, in…

AdS $_{5}$ black strings in the stu model of FI-gauged $N = 2$ supergravity

Matteo Azzola, Dietmar Klemm, Marco Rabbiosi

We analytically construct asymptotically AdS $_{5}$ black string solutions starting from the four-dimensional domain wall black hole of arXiv:0911.4926. It is shown that its uplift gi…

Hidden Role of Maxwell Superalgebras in the Free Differential Algebras of D=4 and D=11 Supergravity

L. Ravera

The purpose of this paper is to show that the so-called Maxwell superalgebra in four dimensions, which naturally involves the presence of a nilpotent fermionic generator, can be in…
