The t t-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 inverse femtobarns collected with the CMS detector
at the LHC. An inclusive and three differential measurements of the t t-bar
charge asymmetry as a function of rapidity, transverse momentum, and invariant
mass of the t t-bar system are presented. The measured inclusive t t-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.
