Muon reconstruction efficiency and momentum resolution of the ATLAS experiment in proton–proton collisions at √s=7 TeV in 2010

Georges Aad, +2900 more
- 16 Sep 2014 - 
TL;DR: In this article, the performance of the muon reconstruction in the analysis of proton-proton collisions at root s = 7TeV at the LHC was described in terms of reconstruction and isolation efficiencies and momentum resolutions for different classes of reconstructed muons.
Journal ArticleDOI

Search for direct top squark pair production in events with a Z boson, b -jets and missing transverse momentum in √s = 8 TeV pp collisions with the ATLAS detector

Georges Aad, +2882 more
- 03 Jun 2014 - 
TL;DR: In this article, a search for direct top squark pair production using events with at least two leptons including a same-flavour opposite-sign pair with invariant mass consistent with the boson mass, jets tagged as originating from -quarks and missing transverse momentum is performed with proton-proton collision data at collected with the ATLAS detector at the LHC in 2012.
Journal ArticleDOI

Search for Dark Matter in Events with Missing Transverse Momentum and a Higgs Boson Decaying to Two Photons in pp Collisions at s=8 TeV with the ATLAS Detector

Georges Aad, +2834 more
- 22 Sep 2015 - 
TL;DR: Results of a search for new phenomena in events with large missing transverse momentum and a Higgs boson decaying to two photons are reported and exclusion limits are presented for models of physics beyond the standard model featuring dark-matter candidates.
Journal ArticleDOI

Search for top quark decays t → qH with H → γγ using the ATLAS detector

Georges Aad, +2931 more
- 03 Jun 2014 - 
TL;DR: In this paper, a search for flavour-changing neutral currents in the decay of a top quark to an up-type quark and a Higgs boson was performed.
Journal ArticleDOI

Measurement of the top quark pair production cross section in pp collisions at s=7TeV in dilepton final states with ATLAS

Georges Aad, +3024 more
- 07 Feb 2012 - 
TL;DR: A measurement of the production cross section of top quark pairs (ttbar) in proton-proton collisions at a center-of-mass energy of 7 TeV recorded with the ATLAS detector at the Large Hadron Collider is reported in this article.
