Measurement of the production cross section of prompt J/ψ mesons in association with a W± boson in pp collisions at √s = 7 TeV with the ATLAS detector

Georges Aad, +2936 more
- 28 Apr 2014 - 
TL;DR: In this article, the authors measured the production cross section of prompt j/psi mesons in association with a W (+/-) boson in pp collisions root s=7 TeV with the ATLAS detector.
Journal ArticleDOI

A search for high-mass resonances decaying to τ+τ- in pp collisions at √s=7 TeV with the ATLAS detector

Georges Aad, +2898 more
- 25 Feb 2015 - 
TL;DR: In this article, a search for high-mass resonances decaying into tau(+)tau(-) final states using proton-proton collisions at root s = 7 TeV produced by the Large Hadron Collider is presented.
Journal ArticleDOI

Determination of the top-quark pole mass using tt̄ + 1-jet events collected with the ATLAS experiment in 7 TeV pp collisions

Georges Aad, +2881 more
- 19 Oct 2015 - 
TL;DR: In this article, the normalized differential cross section for top-quark pair production in association with at least one jet is studied as a function of the inverse of the invariant mass of the t (t) over bar + 1-jet system.
Journal ArticleDOI

Search for supersymmetry in events with three leptons and missing transverse momentum in √s=7TeV pp collisions with the ATLAS detector

Georges Aad, +2914 more
- 29 Jun 2012 - 
TL;DR: A search for the weak production of charginos and neutralinos decaying to a final state with three leptons (electrons or muons) and missing transverse momentum is presented and observations are consistent with standard model expectations in two signal regions that are either depleted or enriched in Z-boson decays.
Journal ArticleDOI

A search for tt̄ resonances in lepton+jets events with highly boosted top quarks collected in pp collisions at √s = 7TeV with the ATLAS detector

Georges Aad, +2914 more
- 13 Sep 2012 - 
TL;DR: In this paper, a search for resonant production of high-mass top-quark pairs is performed on 2.05 fb(-1) of proton-proton collisions at root s = 7 TeV collected in 2011 with the ATLAS experiment at the Large Hadron Collider.
