Journal ArticleDOI

Observation of a new χb state in radiative transitions to Y(1S) and Y(2S) at ATLAS

Georges Aad, +3068 more
TL;DR: The χb(nP) quarkonium states are produced in proton-proton collisions at the Large Hadron Collider at √s=7 TeV and recorded by the ATLAS detector as mentioned in this paper.
Journal ArticleDOI

Measurement of ZZ production in pp collisions at √ = 7 TeV and limits on anomalous ZZZ and ZZγ couplings with the ATLAS detector

Georges Aad, +2941 more
TL;DR: In this paper, a measurement of the ZZ production cross section in proton-proton collisions at root s = 7 TeV using data recorded by the ATLAS experiment at the Large Hadron Collider is presented.
Journal ArticleDOI

Search for strong production of supersymmetric particles in final states with missing transverse momentum and at least three b-jets at √s = 8 TeV proton-proton collisions with the ATLAS detector

Georges Aad, +2920 more
TL;DR: The results are interpreted in the context of several supersymmetric models involving gluinos and scalar top and bottom quarks, as well as a mSUGRA/CMSSM model, significantly extending the previous ATLAS limits.
Journal ArticleDOI

Search for dilepton resonances in pp collisions at √s=7 TeV with the ATLAS detector.

Georges Aad, +3052 more
TL;DR: This Letter reports on a search for narrow high-mass resonances decaying into dilepton final states at the Large Hadron Collider, recorded by the ATLAS experiment in pp collisions at √s=7 TeV.
Journal ArticleDOI

Measurement of the top quark pair production cross-section with ATLAS in the single lepton channel

Georges Aad, +3034 more
- 15 May 2012 - 
TL;DR: A measurement of the production cross-section for top quark pairs (t (t) over bar) in pp collisions at root s = 7 TeV is presented in this paper using data recorded with the ATLAS detector at the Large Hadron Co.
