Abstract
We investigate the predictive power of Collins, Soper, and Sterman's -space QCD resummation formalism for transverse momentum () distributions of heavy boson production in hadronic collisions. We show that the predictive power of the resummation formalism has a strong dependence on the collision energy in addition to its well-known dependence, and the dependence improves the predictive power at collider energies. We demonstrate that at Tevatron and the LHC energies, the distributions derived from -space resummation are not sensitive to the nonperturbative input at large , and give good descriptions of the distributions of heavy boson production at all transverse momenta .
