Electroweak measurements at the Tevatron

Abstract

The increasing size of the data samples recorded by the CDF and DO experiments at the Tevatron enables studies of a wide range of processes involving the electroweak bosons W and Z. Single boson production is now looked at in terms of differential cross sections such as rapidity or transverse momentum dependence. Diboson production cross-sections are several orders of magnitude smaller than single boson production cross-sections, but all combinations Wgamma, Zgamma, WW and WZ have been observed. ZZ production is expected at a rate just below the observation threshold with current data sample sizes, but this channel is expected to be accessible to the Tevatron experiments soon.
