Measurement of the Lepton Charge Asymmetry in Inclusive W Production in pp Collisions at $\sqrt{s}$ = 7 TeV at the CMS experiment

Lepton charge asymmetry in inclusive $pp \rightarrow W X$ production at $\sqrt{s} = 7~\mbox{TeV}$ has been measured by the CMS detector at the LHC, using 36~$\mbox{pb}^{-1}$ of data. These measurements, performed in both $W \rightarrow e \nu$ and $W \rightarrow \mu \nu$ channels, provide new insights into proton structure functions.
