Jet energy measurement and its systematic uncertainty in proton-proton collisions at s√=7 TeV with the ATLAS detector

Georges Aad, +2917 more
TL;DR: In this article, the jet energy scale and its systematic uncertainty are determined for jets measured with the ATLAS detector using proton-proton collision data with a centre-of-mass energy of [Formula: see text]TeV corresponding to an integrated luminosity of [formula] see text][formula:see text].
Journal ArticleDOI

Electron efficiency measurements with the ATLAS detector using 2012 LHC proton-proton collision data

Morad Aaboud, +87 more
TL;DR: The efficiency to reconstruct and identify electrons at the ATLAS experiment varies from 65 to 95%, depending on the transverse momentum of the electron and background rejection, which is measured in data and evaluated in simulated samples.
Journal ArticleDOI

Performance of missing transverse momentum reconstruction in proton-proton collisions at√s = 7 TeV with atlas

Georges Aad, +5562 more
TL;DR: In this paper, the performance of the missing transverse momentum reconstruction was evaluated using data collected in pp collisions at a centre-of-mass energy of 7 TeV in 2010.
Journal ArticleDOI

Luminosity determination in pp collisions at √s = 8 TeV using the ATLAS detector at the LHC

Morad Aaboud, +2872 more
TL;DR: The luminosity determination for the ATLAS detector at the LHC during pp collisions at s√= 8 TeV in 2012 is presented in this article, where the evaluation of the luminosity scale is performed using several luminometers.
Journal ArticleDOI

Evidence for light-by-light scattering in heavy-ion collisions with the ATLAS detector at the LHC

TL;DR: Light-by-light scattering (gamma gamma -> gamma gamma) is a quantum-mechanical process that is forbidden in the classical theory of electrodynamics.
