The charge asymmetry of W bosons produced in pp̅ collisions at √s=1.96  TeV is sensitive to the ratio of d and u quark distributions in the range of x>0.002 at Q2≈MW2. We propose an analysis technique to directly measure W production charge asymmetry from W→eν events at the Tevatron and show the feasibility for this method using Monte Carlo simulations.
