| Özet |
| This paper presents combinations of inclusive and differential measurements of the charge asymmetry (A C) in top quark pair 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 CHC7 C= 0.005±0.007 (stat)±0.006 (syst) at 7 TeV and A CHC8 C= 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 system at 8 TeV, are consistent with the respective standard model predictions. |
