| 英文摘要 | This paper presents combinations of inclusive and differential measurements of the charge asymmetry (a(c)) in top quark pair (t(t)over-bar) 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(t)over-bar system at 8 tev, are consistent with the respective standard model predictions. |
