| Combination of ATLAS and CMS ttbar charge asymmetry measurements | ||

| 2014 | ||
| Abstract: A combination of measurements of the charge asymmetry in $\mathrm{t\bar{t}}$ events performed by the ATLAS and CMS collaborations is presented. The analyzed datasets of LHC proton collisions at a centre-of-mass energy of \,\mathrm{TeV}$ correspond to an integrated luminosity of .7\,\mathrm{fb}^{-1}$ for ATLAS and .0\,\mathrm{fb}^{-1}$ for CMS. In both analyses events with a lepton+jets signature, i.e. one electron or muon and at least four jets, are analyzed. The resulting combined LHC measurement of the charge asymmetry in $\mathrm{t \bar{t}}$ events at $\sqrt{s} = 7\,\mathrm{TeV}$ is: $A_{C} = 0.005 \pm 0.007 (\mathrm{stat.}) \pm 0.006 (\mathrm{syst.})$ which is consistent with the prediction from the Standard Model. | ||
