Parton Distributions from W+- and Z Production in Polarized pp and pn Collisions at RHIC

Claude Bourrely, Jacques Soffer

We study the production of $W^{\pm }$ and $Z$ gauge bosons in proton-proton and proton-neutron collisions up to a center-of-mass energy $\sqrt{s}=0.5TeV$, in connection with the re…
