Grand Unified Theories (GUTs) are one of the most interesting high-energy completions of
the Standard Model, because they provide a rich, powerful and elegant group-theoretical …

Abstract The Standard Model of particles and fields describes the fundamental particles and
their interactions to high level of precision. The SM is nevertheless considered to be a low …

Constraints on selected mediator-based dark matter models and a scalar dark energy model
using up to $37~\mathrm {fb}^{-1} $$\sqrt s= 13$ TeV $ pp $ collision data collected by the …

Results are presented from a search for the direct electroweak production of charginos and
neutralinos in signatures with either two or more leptons (electrons or muons) of the same …

A bstract Results are presented from a search for the direct electroweak production of
charginos and neutralinos in signatures with either two or more leptons (electrons or muons) …

A search for a right-handed gauge boson WR, decaying into a boosted right-handed heavy
neutrino NR, in the framework of Left-Right Symmetric Models is presented. It is based on …

A bstract A statistical combination of several searches for the electroweak production of
charginos and neutralinos is presented. All searches use proton-proton collision data …

A search for four-top-quark production, $ t\bar {t} t\bar {t} $, is presented. It is based on proton-
proton collision data with a center-of-mass energy $\sqrt {s} $= 13 TeV collected by the …

A bstract A search for supersymmetry targeting the direct production of winos and higgsinos
is conducted in final states with either two leptons (e or μ) with the same electric charge, or …

Constraints on selected mediator-based dark matter models and a scalar dark energy model
using up to 37 fb− 1 s= 13 TeV pp collision data collected by the ATLAS detector at the LHC …
