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

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.
Journal ArticleDOI

Hunt for new phenomena using large jet multiplicities and missing transverse momentum with ATLAS in 4.7 fb-1 of √s = 7 TeV proton-proton collisions

Georges Aad, +2894 more
- 27 Jul 2012 - 
TL;DR: In this paper, a search for new particles decaying to large numbers of jets in association with missing transverse momentum, using 4.7 fb(-1) of pp collision data at root s = 7 TeV collected by the ATLAS experiment at the Large Hadron Collider in 2011, is presented.
Journal ArticleDOI

Observation of spin correlation in tt̄ events from pp collisions at √s=7TeV Using the ATLAS detector

Georges Aad, +3100 more
- 24 May 2012 - 
TL;DR: A measurement of spin correlation in t (t) over bar production is reported using data collected with the ATLAS detector at the LHC, corresponding to an integrated luminosity of 2.1 fb(-1) as discussed by the authors.
