dc.description.abstractAbstract: This paper presents combinations of inclusive and di erential measurements of the charge asymmetry (AC) in top quark pair (t t) 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 ALHC7 C = 0:005 0:007 (stat) 0:006 (syst) at 7TeV and ALHC8 C = 0:0055 0:0023 (stat) 0:0025 (syst) at 8TeV. These values, as well as the combination of AC measurements as a function of the invariant mass of the t t system at 8TeV, are consistent with the respective standard model predictions.en
