We present a measurement of the W boson production charge asymmetry in pp-bar→W+X→eν+X events at a center of mass energy of 1.96 TeV, using 9.7 fb(−1) of integrated luminosity collected with the D0 detector at the Fermilab Tevatron Collider. The neutrino longitudinal momentum is determined by using a neutrino weighting method, and the asymmetry is measured as a function of the W boson rapidity. The measurement extends over wider electron pseudorapidity region than previous results and is the most precise to date, allowing for precise determination of proton parton distribution functions in global fits.
