Wilson loops in antisymmetric representations from localization in supersymmetric gauge theories

Jorge Russo, Konstantin Zarembo

Large-N phase transitions occurring in massive N=2 theories can be probed by Wilson loops in large antisymmetric representations. The logarithm of the Wilson loop is effectively de…

Towards an explicit model of large field inflation

Juan Diaz Dorronsoro, Marjorie Schillo

The unwinding inflation mechanism is studied in a type IIB flux compactification where all moduli are stabilized using flux, non-perturbative effects, and the leading alpha' correc…

Complete sets of logarithmic vector fields for integration-by-parts identities of Feynman integrals

Janko Boehm, Alessandro Georgoudis, Kasper J. Larsen +2

Integration-by-parts identities between loop integrals arise from the vanishing integration of total derivatives in dimensional regularization. Generic choices of total derivatives…

Cyclic Mario Worlds -- Color-Decomposition for One-Loop QCD

Gregor Kälin

We present a new color decomposition for QCD amplitudes at one-loop level as a generalization of the Del Duca-Dixon-Maltoni and Johansson-Ochirov decomposition at tree level. Start…

Observational signatures from horizonless black shells imitating rotating black holes

Ulf Danielsson, Suvendu Giri

In arXiv:1705.10172 it was proposed that string theory replaces Schwarzschild black holes with horizonless thin shells with an AdS interior. In this paper we extend the analysis to…

Dongmin Gang, Pietro Longhi, Masahito Yamazaki

We study a realization of S dualities of four-dimensional $N = 2$ class $S$ theories based on BPS graphs. S duality transformations of the UV curve are explicitly…

Five-dimensional fermionic Chern-Simons theory

Dongsu Bak, Andreas Gustavsson

We study 5d fermionic CS theory with a fermionic 2-form gauge potential. This theory can be obtained from 5d MSYM theory by performing the maximal topological twist. We put the the…

Gauged supergravities and spontaneous SUSY breaking from the double copy

Marco Chiodaroli, Murat Gunaydin, Henrik Johansson +1

Supergravities with gauged R-symmetry and Minkowski vacua allow for spontaneous supersymmetry breaking and, as such, provide a framework for building supergravity models of phenome…

Konishi OPE coefficient at the five loop order

Alessandro Georgoudis, Vasco Goncalves, Raul Pereira

We use the method of asymptotic expansions to study the OPE limit of a four-point function of protected operators in N=4 SYM. We use a new method for evaluating the resulting propa…

7D supersymmetric Yang-Mills on curved manifolds

Konstantina Polydorou, Andreas Rocén, Maxim Zabzine

We study 7D maximally supersymmetric Yang-Mills theory on curved manifolds that admit Killing spinors. If the manifold admits at least two Killing spinors (Sasaki-Einstein manifold…
