Abstract
The t (t) over bar 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 5.0 fb(-1) collected with the CMS detector at the LHC. An inclusive and three differential measurements of the t (t) over bar charge asymmetry as a function of rapidity, transverse momentum, and invariant mass of the t (t) over bar system are presented. The measured inclusive t (t) over bar charge asymmetry is A(C) = 0.004 +/- 0.010 (stat.) +/- 0.011 (syst.). This result and the three differential measurements are consistent with zero asymmetry as well as with the predictions of the standard model.
