Search for dark matter and other new phenomena in events with an energetic jet and large missing transverse momentum using the ATLAS detector

Morad Aaboud, +2957 more
- 25 Jan 2018 - 
TL;DR: In this paper, a search for new phenomena in final states with an energetic jet and large missing transverse momentum is reported, and the results are translated into exclusion limits in models with pair-produced weakly interacting dark-matter candidates, large extra spatial dimensions, and supersymmetric particles in several compressed scenarios.
Journal ArticleDOI

Evidence for light-by-light scattering in heavy-ion collisions with the ATLAS detector at the LHC

Morad Aaboud, +86 more
- 14 Aug 2017 - 
TL;DR: Light-by-light scattering (gamma gamma -> gamma gamma) is a quantum-mechanical process that is forbidden in the classical theory of electrodynamics.
Journal ArticleDOI

Search for electroweak production of charginos and sleptons decaying into final states with two leptons and missing transverse momentum in √s = 13 TeV pp collisions using the ATLAS detector

Georges Aad, +2937 more
- 14 Feb 2020 - 
TL;DR: In this article, a search for the electroweak production of charginos and sleptons decaying into final states with two electrons or muons is presented, based on 139.fb$^{-1}$ of proton-proton collisions recorded by the ATLAS detector at the Large Hadron Collider at
Journal ArticleDOI

Search for new phenomena in dijet events using 37 fb-1 of pp collision data collected at √s=13 TeV with the ATLAS detector

Morad Aaboud, +2909 more
- 01 Sep 2017 - 
TL;DR: In this paper, Dijet events are studied in the proton-proton collision dataset recorded at root s = 13 TeV with the ATLAS detector at the Large Hadron Collider in 2015 and 2016.
Journal ArticleDOI

Combination of searches for invisible Higgs boson decays with the ATLAS experiment

Morad Aaboud, +2939 more
- 13 Jun 2019 - 
TL;DR: An exclusion limit on the H→invisible branching ratio of 0.26(0.17_{-0.05}^{+0.07}) at 95% confidence level is observed (expected) in combination with the results at sqrt[s]=7 and 8 TeV.
