Search for Quantum Black Hole Production in High-Invariant-Mass Lepton + Jet Final States Using pp Collisions at √s = 8 TeV and the ATLAS Detector

Georges Aad, +2963 more
- 05 Mar 2014 - 
TL;DR: This Letter presents a search for quantum black-hole production using 20.3 fb-1 of data collected with the ATLAS detector in pp collisions at the LHC at √s = 8 TeV to set limits on the product of cross sections and branching fractions for the lepton+jet final states of quantum black holes produced in a search region for invariant masses above 1 TeV.
Journal ArticleDOI

Georges Aad, +2836 more
- 07 Oct 2015 - 
TL;DR: In this paper, a measurement of the exclusive gamma gamma = l(+)l(-) (l = e, mu) cross-section in proton-proton collisions at a centre-of-mass energy of 7 TeV by the ATLAS experiment at the LHC, based on an integrated luminosity of 4.6 fb(-1).

Search for dark matter produced in association with a Higgs boson decaying to two bottom quarks in pp collisions at √s = 8 TeV with the ATLAS detector

Georges Aad, +2870 more
- 18 Apr 2016 - 
TL;DR: In this paper, a search for dark matter pair production in association with a Higgs boson decaying to a pair of bottom quarks was conducted using data from 20.3 fb(-1) of pp collisions at a center-of-m...

Search for TeV-scale gravity signatures in high-mass final states with leptons and jets with the ATLAS detector at s = 13 TeV

Georges Aad, +3075 more
- 17 Sep 2012 - 
TL;DR: In this paper, a search for physics beyond the Standard Model, in final states with at least one high transverse momentum charged lepton (electron or muon) and two additional high-transverse momentum leptons or jets, was performed using 3.2 fb−1 of proton-proton collision data recorded by the ATLAS detector at the Large Hadron Collider in 2015 at √s = 13 TeV.
