Measurement of the Muon Charge Asymmetry in the $\ppWmn$ process at \rts~=~14 TeV.

We present estimates for the measurement of the muon charge asymmetry in $\Wmn$ events with the Compact Muon Solenoid (CMS) detector at the Large Hadron Collider (LHC). We consider proton-proton collision data at center-or-mass energy $\rts$=14 TeV for integrated luminosities in the range 10 to 100 \pbinv. The muon charge asymmetry is studied in the pseudo-rapidity region, $|\eta|<2$.
