Abstract
We study the nonperturbative functions in the Collins-Soper-Sterman resummation formalism by examining Drell-Yan data in both fixed target and collider experiments and then predict the transverse momentum distributions of the ${\mathit{W}}^{\ifmmode\pm\else\textpm\fi{}}$ and ${\mathit{Z}}^{0}$ bosons at the Fermilab Tevatron. Our results differ from those in the literature and agree better with published CDF data. Using statistical arguments, we find a 1 ${\mathrm{fb}}^{\mathrm{\ensuremath{-}}1}$ luminosity at the Tevatron should be able to provide useful constraints on the nonperturbative functions.
