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.
Journal ArticleDOI

Search for resonances decaying into top-quark pairs using fully hadronic decays in pp collisions with ATLAS at √s=7 TeV

Georges Aad, +2945 more
- 12 Feb 2013 - 
TL;DR: In this paper, a search for resonances produced in 7 TeV proton-proton collisions and decaying into top-quark pairs is described, where two techniques that rely on jet substructure are used to separate top quark jets from those arising from light quarks and gluons.
Journal ArticleDOI

Measurement of the jet fragmentation function and transverse profile in proton-proton collisions at a center-of-mass energy of 7 TeV with the ATLAS detector

Georges Aad, +3005 more
- 30 Nov 2011 - 
TL;DR: In this paper, the jet fragmentation function and transverse profile for jets with 25 GeV < p(Tjet) < 500 GeV and |eta(jet)| < 1.2 produced in proton-proton collisions with a center-of-mass energy of 7 TeV are presented.
Journal ArticleDOI

Search for squarks and gluinos in events with isolated leptons, jets and missing transverse momentum at √s = 8 TeV with the ATLAS detector

Georges Aad, +2927 more
- 21 Apr 2015 - 
TL;DR: The results of a search for supersymmetry in final states containing at least one isolated lepton (electron or muon), jets and large missing transverse momentum with the ATLAS detector at the Large Hadron Collider are reported in this paper.
Journal ArticleDOI

Measurement of the double-differential high-mass Drell-Yan cross section in pp collisions at √s = 8 TeV with the ATLAS detector

Georges Aad, +2918 more
- 01 Aug 2016 - 
TL;DR: In this article, a measurement of the double-differential cross section for the Drell-Yan Z/γ∗ → l+l− and photon-induced γγ → l + l− processes where l is an electron or muon was performed for invariant masses of the lepton pairs, mll, between 116 GeV and 1500 GeV.
