Signatures of the Type-I 2HDM at the LHC

Rikard Enberg, William Klemm, Stefano Moretti +1

One of the simplest extensions of the Standard Model (SM) is the two-Higgs-doublet model (2HDM), which contains two neutral Higgs bosons, in addition to a 125 GeV one, and a charge…

Dyson equations for correlators of Wilson loops

Diego Correa, Pablo Pisani, Alan Rios Fukelman +1

By considering a Gaussian truncation of $N = 4$ super Yang-Mills, we derive a set of Dyson equations that account for the ladder diagram contribution to connected correlators…

Non-Abelian gauged supergravities as double copies

Marco Chiodaroli, Murat Gunaydin, Henrik Johansson +1

Scattering amplitudes have the potential to provide new insights to the study of supergravity theories with gauged R-symmetry and Minkowski vacua. Such gaugings break supersymmetry…

Variations of the elephant random walk

Allan Gut, Ulrich Stadtmüller

In the classical simple random walk the steps are independent, viz., the walker has no memory. In contrast, in the elephant random walk which was introduced by Schütz and Trimper i…
