dc.description.abstractThis paper presents combinations of inclusive and differential measurements of the charge asymmetry (\(A_C\)) in top quark pair \(\left(t\overline{t}\right)\) events with a lepton+jets signature by the ATLAS and CMS Collaborations, using data from LHC proton-proton collisions at centre-of-mass energies of 7 and 8 TeV. 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 \(A_C^{LHC7}\) = 0.005 ± 0.007 (stat) ± 0.006(syst) at 7 TeV and \(A_C^{LHC8}\) = 0.0055 ± 0.0023 (stat) ± 0.0025 (syst) at 8 TeV. These values, as well as the combination of (\(A_C\)) measurements as a function of the invariant mass of the \(t\overline{t}\) system at 8 TeV, are consistent with the respective standard model predictions.en_US
