We analyze the role of the nonperturbative input in the Collins, Soper, andSterman (CSS)'s $b$-space QCD resummation formalism for Drell-Yan transversemomentum ($Q_T$) distributions, and investigate the predictive power of the CSSformalism. We find that the predictive power of the CSS formalism has a strongdependence on the collision energy $\sqrt{S}$ in addition to its well-known$Q^2$ dependence, and the $\sqrt{S}$ dependence improves the predictive powerat collider energies. We show that a reliable extrapolation from perturbativelyresummed $b$-space distributions to the nonperturbative large $b$ region isnecessary to ensure the correct $Q_T$ distributions. By adding powercorrections to the renormalization group equations in the CSS formalism, wederive a new extrapolation formalism. We demonstrate that at collider energies,the CSS resummation formalism plus our extrapolation has an excellentpredictive power for $W$ and $Z$ production at all transverse momenta $Q_T\leQ$. We also show that the $b$-space resummed $Q_T$ distributions provide a gooddescription of Drell-Yan data at fixed target energies.Comment: Latex, 43 pages including 15 figures; typos were correcte
