Abstract: We report on a measurement of the muon charge asymmetry in inclusive pp$\rightarrow$W+X production at $\sqrt{s}$=7 TeV. The data sample corresponds to an integrated luminosity of 4.7 $\mathrm{fb}^{-1}$ recorded by the CMS detector at the LHC. With a sampleof more than 20 million $\mathrm{W}\rightarrow \mu\nu$ events, the statistical precision is greatly improved in comparison to previous measurements. These new results provide additional constraints on the Parton Distribution Functions~(PDFs) in the proton in the Bj\"{o}rken parameter $x$ range from 0.001 to 0.1. | ||
