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.
Journal ArticleDOI

Search for H→γγ produced in association with top quarks and constraints on the Yukawa coupling between the top quark and the Higgs boson using data taken at 7 TeV and 8 TeV with the ATLAS detector

Georges Aad, +3099 more
- 05 Jan 2015 - 
TL;DR: In this article, a search is performed for Higgs bosons produced in association with top quarks using the diphoton decay mode of the Higgs Boson using the ATLAS detector at the CERN Large Hadron Collider, which corresponds to an integrated luminosity of 4.5 fb(-1) of proton-proton collisions at a center-of-mass energy of 7 TeV and 20.3 fb (-1) at 8 TeV.
Journal ArticleDOI

Cross-section measurements of the Higgs boson decaying into a pair of τ-leptons in proton-proton collisions at √s=13 TeV with the ATLAS detector

Morad Aaboud, +2928 more
- 10 Apr 2019 - 
TL;DR: In this article, a measurement of production cross sections of the Higgs boson in proton-proton collisions is presented in the H→ττ decay channel, and the analysis is performed using 36.1 fb-1 of data recorded by the ATLAS experiment at the Large Hadron Collider at a center of mass energy of s=13 TeV.
Journal ArticleDOI

Constraints on the off-shell Higgs boson signal strength in the high-mass ZZ and WW final states with the ATLAS detector

Georges Aad, +2811 more
- 17 Jul 2015 - 
TL;DR: Constraints on the off-shell Higgs boson event yields normalised to the Standard Model prediction (signal strength) in the ZZ and WW final states in the mass range above the 2mZ and 2mW thresholds are presented.
Journal ArticleDOI

Search for a supersymmetric partner to the top quark in final states with jets and missing transverse momentum at √s=7 TeV with the ATLAS Detector

Georges Aad, +2942 more
- 20 Nov 2012 - 
TL;DR: A search for direct pair production of supersymmetric top squarks (t(1)) is presented, assuming the t(1) decays into a top quark and the lightest supers asymmetric particle, χ(1)(0), and that both top quarks decay to purely hadronic final states.
