We investigate the predictive power of the Collins, Soper, and Sterman b -space QCD resummation formalism for transverse momentum (Q{sub T}) distributions of heavy boson production in hadronic collisions. We show that the predictive power has a strong dependence on the collision energy S in addition to its well known Q{sup 2} dependence, and the S dependence improves the predictive power at collider energies. We demonstrate that, at the Fermilab Tevatron and the CERN LHC energies, the Q{sub T} distributions derived from b -space resummation are not sensitive to the nonperturbative input at large b , and give good descriptions of the Q{sub T} distributions of heavy boson production at all transverse momenta Q{sub T}{<=}Q .
