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 CHC7 ?=?0.005?± 0.007 (stat)?± 0.006(syst) at 7 TeV and A C CHC8 ?=?0.0055 ± 0.0023 (stat) ± 0.0025 (syst) at 8 TeV. These values, as well as the combination of AC measurements as a function of the invariant mass of the tt¯ system at 8 TeV, are consistent with the respective standard model predictions.
