The STAR W+/W- cross section ratio is minimally affected by fiducial constraints and pT resummation, providing robust discrimination between ar d(x) and ar u(x) PDF models at x ~ 0.1 via L2 sensitivity and reweighting.

abstract
An up-to-date global QCD analysis of high energy lepton-hadron and hadron-hadron interactions is performed to better determine the gluon and quark parton distributions in the nucleon. Improved experimental data on inclusive jet production, in conjunction with precise deep inelastic scattering data, place good constraints on the gluon over a wide range of x; while new data on asymmetries in Drell-Yan processes contribute to better determine the d/u ratio. Comparisons with results of other recent global analyses are made, and the differences are described. Open issues and the general problem of determining the uncertainties of parton distributions are discussed.
