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.
Journal ArticleDOI

Measurement of the forward-backward asymmetry of electron and muon pair-production in pp collisions at √s=7 TeV with the ATLAS detector

Georges Aad, +2872 more
- 09 Sep 2015 - 
TL;DR: In this article, measurements from the ATLAS experiment of the forward-backward asymmetry in the reaction pp -> Z/gamma* -> l(+)l(-, with l being electrons or muons, and the extraction of the effective weak mixing angle.
Journal ArticleDOI

Measurement of the t(t)over-bar production cross section in the tau plus jets channel using the ATLAS detector

Georges Aad, +2883 more
- 02 Mar 2013 - 
TL;DR: In this article, a measurement of the top quark pair production cross section in the final state with a hadronically decaying tau lepton and jets is presented, based on proton-proton collision data recorded by the ATLAS experiment at the LHC, with a centre-of-mass energy of 7 TeV.
Journal ArticleDOI

Search for bottom squark pair production in proton–proton collisions at √s=13 TeV with the ATLAS detector

Morad Aaboud, +2860 more
- 06 Oct 2016 - 
TL;DR: Exclusion limits at 95 % confidence level on the mass of the bottom squark are derived in phenomenological supersymmetric R-parity-conserving models in which the lightest squark b~1 is the lightmost squark and is assumed to decay exclusively via b-quarks.
Journal ArticleDOI

Measurements of jet vetoes and azimuthal decorrelations in dijet events produced in pp collisions at √s = 7 TeV using the ATLAS detector

Georges Aad, +2870 more
- 31 Oct 2014 - 
TL;DR: In this paper, additional jet activity in dijet events is measured using pp collisions at ATLAS at a centre-of-mass energy of 7 TeV, for jets reconstructed using the anti-k(t) algorithm with radius parameter R = 0.6.
