| Publication Abstract: | We present a new parton distribution function analysis which includes new data for W boson production in proton-proton collisions and lepton pair production in proton-proton and proton-deuteron collisions. The new data provide strong constraints on the light antiquark parton distribution functions in the proton. We identify an interesting correlation between the d/u ratio and the dbar/ubar ratio which leads to a modification of our previous results for the d/u ratio as the parton momentum fraction x --> 1. |
