Journal ArticleDOI

Search for nonpointing photons in the diphoton and E-T(miss) final state in root s=7 TeV proton-proton collisions using the ATLAS detector

Georges Aad, +2900 more
- 01 Jul 2013 - 
TL;DR: In this paper, a search for photons originating in the decay of a neutral long-lived particle was performed, exploiting the capabilities of the ATLAS electromagnetic calorimeter to make precise measurements of the flight direction of photons, as well as the calorimeters excellent time resolution.
Journal ArticleDOI

Search for Higgs boson decays into a pair of pseudoscalar particles in the bbμμ final state with the ATLAS detector in pp collisions at s=13  TeV

Georges Aad, +2846 more
TL;DR: In case of a legitimate complaint, the Library will make the material inaccessible and/or remove it from the website as discussed by the authors , in case of legitimate complaints the material will be removed.
Journal ArticleDOI

Measurement of detector-corrected observables sensitive to the anomalous production of events with jets and large missing transverse momentum in pp collisions at √s=13 TeV using the ATLAS detector

Morad Aaboud, +2884 more
- 15 Nov 2017 - 
TL;DR: In this article, an observable ratio of cross sections is defined for events containing jets and large missing transverse momentum in the plane transverse to the proton beams at the Large Hadron Collider, which can be used to constrain new physics models beyond those shown in this paper.
Journal ArticleDOI

Search for the Production of a Long-Lived Neutral Particle Decaying within the ATLAS Hadronic Calorimeter in Association with a Z Boson from pp Collisions at √s = 13 TeV

Morad Aaboud, +2949 more
- 15 Apr 2019 - 
TL;DR: This Letter presents a search for the production of a long-lived neutral particle (Z_{d}) decaying within the ATLAS hadronic calorimeter, in association with a standard model (SM) Z boson produced via an intermediate scalar boson, where Z→ℓ^{+}⚓^{-} ( ℓ=e, μ).
Journal ArticleDOI

Measurement of the CP-violating phase ϕs in Bs0→J/ψϕ decays in ATLAS at 13 TeV

Georges Aad, +2972 more
- 01 Apr 2021 - 
TL;DR: A measurement of the Bs0→J/ψϕ decay parameters using 80.5fb-1 of integrated luminosity collected with the ATLAS detector from 13-Te proton-proton collisions at the LHC is presented in this paper.
