Inclusive and differential measurements of the tt- charge asymmetry in proton-proton collisions at s=7 TeV

Abstract: The charge asymmetry is measured in events containing a charged lepton (electron or muon) and at least four jets, one of which is identified as originating from b-quark hadronization. The analyzed dataset corresponds to an integrated luminosity of collected with the CMS detector at the LHC. An inclusive and three differential measurements of the charge asymmetry as a function of rapidity, transverse momentum, and invariant mass of the system are presented. The measured inclusive charge asymmetry is . This result and the three differential measurements are consistent with zero asymmetry as well as with the predictions of the standard model.
