Title: Bloch-Nordsieck regularization of QCD transverse-momentum distributions

Abstract

An expression for transverse-momentum distributions is presented for Drell-Yan-type processes: it is infrared finite, includes soft-gluon summation in the leading-logarithmic approximation and reproduces the first-order perturbative results at large {ital p}{sub {ital T}}. In addition, our expression incorporates soft QCD radiative corrections to that part of the cross section where hard bremsstrahlung dominates. We compute {ital W} transverse-momentum distributions and average values for a set of different energies: {radical}{ital s} =630 GeV, 1.8 TeV, 6 TeV, and 18 TeV.
