We predict W and Z transverse momentum distributions from proton-proton andnuclear collisions at RHIC and LHC. A resummation formalism with powercorrections to the renormalization group equations is used. The dependence ofthe resummed QCD results on the non-perturbative input is very weak for thesystems considered. Shadowing effects are discussed and found to be unimportantat RHIC, but important for LHC. We study the enhancement of power correctionsdue to multiple scattering in nuclear collisions and numerically illustrate theweak effects of the dependence on the nuclear mass.Comment: 21 pages, 11 figure
