Scale Evolution of Unintegrated Distributions and the p_t Spectrum of Gauge Bosons

Abstract

We present predictions for the $Z$-boson $p_t$-spectrum at Tevatron within the framework of unintegrated distributions evolved according to evolution equations recently proposed by us. We discuss the dependence of the results on the choice of non-perturbative parameters, the coupling constant and the impact of soft gluon resummation.
