Description

We present a measurement of the lepton charge asymmetry in pp->W->lnu decays at sqrt(s)=7 TeV with the CMS detector at the LHC. Results are presented corresponding to 36 pb^-1 of integrated luminosity for both the electron and muon channels in 6 bins of lepton pseudorapidity up to |eta|=2.4 and |eta|=2.1 respectively. The measurements are compared with theoretical predictions and the results are expected to provide additional constraints on the parton distribution functions of the proton.
