Vector Boson Production at Hadron Colliders: Results from HERWIG and Resummed Calculations

Abstract

We discuss vector boson production at hadron colliders and the treatment of the initial-state radiation according to Monte Carlo parton shower simulations and resummed calculations. In particular, we investigate the effect of matrix-element corrections to the HERWIG event generator on W/Z transverse momentum distributions.
