This paper presents combinations of inclusive and differential measurements of the charge asymmetry (A C ) in top quark pair (tt) events with a lepton+jets signature by the ATLAS and CMS Collaborations, using data from LHC proton-proton collisions at centreof- mass energies of 7 and 8TeV. The data correspond to integrated luminosities of about 5 and 20 fb –1 for each experiment, respectively. The resulting combined LHC measurements of the inclusive charge asymmetry are A CLHC7 = 0:005±0:007 (stat) ±0:006 (syst) at 7TeV and A CLHC7 = 0:0055 ± 0:0023 (stat) ± 0:0025 (syst) at 8TeV. These values, as well as the combination of A C measurements as a function of the invariant mass of the [formula presented] system at 8TeV, are consistent with the respective standard model predictions.

Abstract

This paper presents combinations of inclusive and differential measurements of the charge asymmetry (A C ) in top quark pair (tt) events with a lepton+jets signature by the ATLAS and CMS Collaborations, using data from LHC proton-proton collisions at centreof- mass energies of 7 and 8TeV. The data correspond to integrated luminosities of about 5 and 20 fb –1 for each experiment, respectively. The resulting combined LHC measurements of the inclusive charge asymmetry are A CLHC7 = 0:005±0:007 (stat) ±0:006 (syst) at 7TeV and A CLHC7 = 0:0055 ± 0:0023 (stat) ± 0:0025 (syst) at 8TeV. These values, as well as the combination of A C measurements as a function of the invariant mass of the [formula presented] system at 8TeV, are consistent with the respective standard model predictions.
