BlochNordsieck regularization of QCD transversemomentum distributions
Abstract
An expression for transversemomentum distributions is presented for DrellYantype processes: it is infrared finite, includes softgluon summation in the leadinglogarithmic approximation and reproduces the firstorder 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} transversemomentum distributions and average values for a set of different energies: {radical}{ital s} =630 GeV, 1.8 TeV, 6 TeV, and 18 TeV.
