Search for Diphoton Events with Large Missing Transverse Energy with 36 pb^-1 of 7 TeV Proton-Proton Collision Data with the ATLAS Detector

Georges Aad, +3143 more
- 01 Oct 2011 - 
TL;DR: In this paper, the ATLAS Collaboration performed a search for diphoton events with large missing transverse energy, and a 95% Confidence Level (CL) upper limit on the cross section for new physics of sigma 961 GeV is set on the UED compactification radius R.
Journal ArticleDOI

Search for dark matter in association with an energetic photon in pp collisions at √s = 13 TeV with the ATLAS detector

Georges Aad, +3007 more
- 25 Feb 2021 - 
TL;DR: In this paper, a search for dark matter is conducted in final states containing a photon and missing transverse momentum in proton-proton collisions at the CERN LHC, and 95% confidence-level upper limits between 2.45 fb and 0.5 fb are set on the visible cross section for contributions from physics beyond the Standard Model, in different ranges of the missing transversal momentum.
Journal ArticleDOI

Alignment of the ATLAS Inner Detector in Run 2

Georges Aad, +2964 more
- 01 Dec 2020 - 
TL;DR: In this paper, the performance of the ATLAS Inner Detector alignment has been studied using pp collision data at s=13TeV collected by the LHC experiment during Run 2 (2015-2018) of the Large Hadron Collider.
Journal ArticleDOI

Measurement of J/ψ production in association with a W ± boson with pp data at 8 TeV

Morad Aaboud, +2961 more
- 16 Jan 2020 - 
TL;DR: In this paper, a measurement of the production of a prompt J/psi meson in association with a W-+/- boson with W−/- -> mu nu and J−psi -> mu(+)mu(-) is presented.
Journal ArticleDOI

Search for pair production of scalar leptoquarks decaying into first- or second-generation leptons and top quarks in proton–proton collisions at √s = 13 TeV with the ATLAS detector

Georges Aad, +2982 more
- 01 Apr 2021 - 
TL;DR: In this paper, a search for pair production of scalar leptoquarks, each decaying into either an electron or a muon and a top quark, is presented.
