摘要

The unique forward LHCb acceptance opens the possibility for performing precision Standard Model processes in a kinematical regime beyond the reach of both ATLAS and CMS experiments. In this article we discuss the feasibility of performing W-+/- j measurements with 14 TeV LHCb data, and find that the leptonic asymmetry at high pseudorapidity, with appropriate cuts on the associated jet, can provide a factor of 3 reduction on the d-quark parton distribution function uncertainty in a region of Bjorken x > 0.5.
