Search for supersymmetry in events with photons, bottom quarks, and missing transverse momentum in proton-proton collisions at a centre-of-mass energy of 7 TeV with the ATLAS detector

Georges Aad, +2884 more
- 26 Feb 2013 - 
TL;DR: In this article, the experimental signature of an isolated photon with high transverse momentum, at least one jet identified as originating from a bottom quark, and high missing transversal momentum was searched using the full dataset of 7 TeV proton-proton collisions recorded with the ATLAS detector at the LHC.
Journal ArticleDOI

Measurement of the t (t)over-bar production cross-section using e mu events with b-tagged jets in pp collisions at root s = 7 and 8 TeV with the ATLAS detector (vol 76, pg 642, 2014)

Georges Aad, +2882 more
- 23 Nov 2016 - 
TL;DR: In this article, the ATLAS measurement of the inclusive top quark pair cross-section was updated using the final 2012 luminosity calibration, which is consistent with theoretical QCD calculations at next-to-next-leading order.
Journal ArticleDOI

Underlying event characteristics and their dependence on jet size of charged-particle jet events in pp collisions at root(s)=7 TeV with the ATLAS detector

Georges Aad, +2909 more
- 09 Oct 2012 - 
TL;DR: In this paper, the authors used the antikt algorithm with radius parameter R varying between 0.2 and 1.0 to reconstruct the trajectories of the charged particle jets at the Large Hadron Collider (LHC).
Journal ArticleDOI

Measurement of the mass difference between top and anti-top quarks in pp collisions at √s = 7 TeV using the ATLAS detector

Georges Aad, +2911 more
- 20 Jan 2014 - 
TL;DR: In this article, a measurement of the mass difference between top and anti-top quarks is presented in a 4.7 fb(-1) data sample of proton-proton collisions at root s = 7 TeV recorded with the ATLAS detector at the...
