Abstract We carefully reexamine the production of gauge bosons such as W ± and Z in pp collisions up to √ s = 0.5 TeV, in connection with the realistic possibility of having polarized proton beams at RHIC with a high luminosity. We stress the importance of measuring unpolarized cross sections and the various parity-violating asymmetries, as a test of our present knowledge on unpolarized and polarized parton distributions, assuming the electroweak Standard Model couplings.
