The asymmetry is measured in the W → µν decay mode as a function of the muon pseudorapidity using a data sample corresponding to a total integrated luminosity of 31 pb −1 . The results are compared to predictions based on next-to-leading order calculations with various parton distribution functions. This measurement provides information on the u and d quark momentum fractions in the proton.
