Analysis of semi-inclusive DIS hadroproduction suggests broadening of transverse momentum distributions at small x below 10-3 {approx} 10-2, which can be modeled in the Collins-Soper-Sterman formalism by a modification of impact parameter dependent parton densities. We investigate these consequences for the production of electroweak bosons at the Tevatron and the LHC. If substantial small-x broadening is observed in forward Z0 boson production in the Tevatron Run-2, it will strongly affect the predicted qT distributions for W{+-} and Z0 boson production at the LHC.
