We predict W^\ifmmode±\else\textpm\fi and Z0 transverse momentum distributions from proton-proton and nuclear collisions at Relativistic Heavy-Ion Collider (RHIC) and Large Hadron Collider (LHC) energies. A resummation formalism with power corrections to the renormalization group equations is used. The dependence of the resummed QCD results on the nonperturbative input is very weak for the systems considered. Shadowing effects are discussed and found to be unimportant at RHIC, but important for LHC. We study the enhancement of power corrections due to multiple scattering in nuclear collisions and numerically illustrate the weak effects of the dependence on the nuclear mass.
