Analysis of small-x semi-inclusive DIS hadroproduction suggests that multiple parton radiation leads to a broadening of transverse momentum distributions beyond that predicted by a straightforward calculation in the Collins-Soper-Sterman formalism. This effect can be modeled by a modification of the resummed form factor in the small-x region. We discuss the impact of such a modification on the production of electroweak bosons at hadron-hadron colliders. We show that if substantial small-x broadening is observed in forward Z boson production in the Tevatron Run-2, it would strongly affect predicted transverse momentum distributions for W, Z, and Higgs boson production at the Large Hadron Collider.
