dc.description.abstract	The tt̄ charge asymmetry in proton-proton collisions at s = 7TeV is measured using the dilepton decay channel (ee, eμ, or μμ). The data correspond to a total integrated luminosity of 5.0 fb-1, collected by the CMS experiment at the LHC. The tt̄ and lepton charge asymmetries, defined as the differences in absolute values of the rapidities between the reconstructed top quarks and antiquarks and of the pseudorapidities between the positive and negative leptons, respectively, are measured to be AC = -0.010 ± 0.017 (stat.) ± 0.008 (syst.) and AClep = 0.009 ± 0.010 (stat.) ± 0.006 (syst.). The lepton charge asymmetry is also measured as a function of the invariant mass, rapidity, and transverse momentum of the tt̄ system. All measurements are consistent with the expectations of the standard model.
