Analysis of events with b-jets and a pair of leptons of the same charge in pp collisions at √s = 8 TeV with the ATLAS detector

Georges Aad, +2864 more
- 01 Oct 2015 - 
TL;DR: In this paper, an analysis of events containing jets including at least one $b$-tagged jet, sizeable missing transverse momentum, and at least two leptons including a pair of the same electric charge, with the scalar sum of the jet and lepton transverse momenta being large.
Journal ArticleDOI

Measurements of b-jet tagging efficiency with the ATLAS detector using tt¯ events at √s=13 TeV

Morad Aaboud, +2980 more
- 01 Aug 2018 - 
TL;DR: In this article, the efficiency of detecting b-hadrons was measured using a high purity sample of dileptonic top quark-antiquark pairs selected from the 36.1 fb$^{−1}$ of data collected by the ATLAS detector in 2015 and 2016 from proton-proton collisions produced by the Large Hadron Collider at a centre-of-mass energy of 13 $ TeV.
Journal ArticleDOI

Measurement of upsilon production in 7 TeV pp collisions at ATLAS

Georges Aad, +2898 more
- 04 Mar 2013 - 
TL;DR: In this article, the production cross sections of Upsilon(1S,2S,3S) mesons are reconstructed using the dimuon decay mode. And the results of the reconstruction are compared to several theoretical models of upsilon meson production, finding that none provide an accurate description of the data over the full range of Upsilicon transverse momenta accessible with this data set.
Journal ArticleDOI

Rapidity gap cross sections measured with the ATLAS detector in pp collisions at √ s =7 TeV

Georges Aad, +3016 more
- 13 Mar 2012 - 
TL;DR: In this article, the pseudorapidity gap distributions in proton-proton collisions at root s = 7 TeV are studied using a minimum bias data sample with an integrated luminosity of 7.1 mu b(-1).
Journal ArticleDOI

Measurement of the $t\bar{t}$ production cross-section using $e\mu$ events with $b$-tagged jets in $pp$ collisions at $\sqrt{s}=7$ and 8 TeV with the ATLAS detector

Georges Aad, +2884 more
- 20 Jun 2014 - 
TL;DR: In this article, the authors measured the top quark pair production cross-section in proton-proton collisions at 7 TeV and 8 TeV with the ATLAS experiment at the LHC, using ttbar events with an opposite-charge e-mu pair in the final state.
