Description

A study has been made of the production characteristics of W and Z bosons produced at the CERN anti pp collider. The event sample consists of 251 W → eν decays, and 39 Z → e+e- decays, identified by the UA2 detector, and corresponds to an integrated luminosity of 142 nb-1 at √s = 546 GeV, and 768 nb-1 at √s = 630 GeV. Measurements of W and Z production cross sections, of longitudinal and transverse momentum distributions, and of associated jet production, are presented. These measurements are compared with theoretical expectations, which include higher order QCD effects. (orig.)
