Measurement of the charge asymmetry in top quark pair production at CMS

The $\mathrm{t\bar{t}}$ charge asymmetry is measured in the lepton$+$jets decay channel using a dataset of 19.7$\mathrm{fb^{-1}}$ collected with the CMS detector at the LHC. We present an inclusive measurement as well as three differential measurements as functions of rapidity ,transverse momentum,...

description The $\mathrm{t\bar{t}}$ charge asymmetry is measured in the lepton$+$jets decay channel using a dataset of 19.7$\mathrm{fb^{-1}}$ collected with the CMS detector at the LHC. We present an inclusive measurement as well as three differential measurements as functions of rapidity ,transverse momentum, and invariant mass of the $\mathrm{t\bar{t}}$ system. The measured inclusive $\mathrm{t\bar{t}}$ charge asymmetry is $ 0.005 \pm 0.007~(\rm{stat.})\,\pm 0.006 ~(\rm{syst.})$; both this result and the differential measurements are consistent with the predictions of the Standard Model.
