Search for Higgs bosons decaying into new spin-0 or spin-1 particles in four-lepton final states with the ATLAS detector with 139 fb−1 of pp collision data at $$ \sqrt{s} $$ = 13 TeV

Georges Aad, +2843 more
- 01 Mar 2022 - 
TL;DR: In this paper , a search for new spin-0 or spin-1 bosons using events where a Higgs boson with mass 125 GeV decays into four leptons ( ℓ = e , μ ).
Journal ArticleDOI

Search for pairs of highly collimated photon-jets in pp collisions at s =13 TeV with the ATLAS detector

Morad Aaboud, +2957 more
- 18 Jan 2019 - 
TL;DR: In this article, the results of a search for the pair production of photon-jets in the ATLAS detector at the Large Hadron Collider are reported, and the results are interpreted in the context of a model containing a new, high-mass scalar particle with narrow width, X, that decays into pairs of photonjets via new, light particles, a upper limits are placed on the cross section times the product of branching ratios σ×B(X→aa)×B (a→γγ)2 for 200 GeV.
Journal ArticleDOI

Georges Aad, +3002 more
- 01 Jan 2021 - 
TL;DR: In this paper, a measurement of event-shape variables in proton-proton collisions at large momentum transfer is presented using data collected at s = 13 TeV with the ATLAS detector at the Large Hadron Collider.
Journal ArticleDOI

Georges Aad, +2983 more
- 01 Oct 2021 - 
TL;DR: In this article, a search for dark matter in the context of a two-Higgs-doublet model together with an additional pseudoscalar mediator, $a$, which decays into the dark-matter particles is presented.
