Findings
Measured W and Z production cross sections
Determined W width and W boson mass
Tested lepton universality with W decays to tau
Abstract
Results from analyses of events with W and Z bosons are presented for the D0 Tevatron run 1B data samples. From the leptonic decays of the W and Z, the W and Z production cross sections and the W width are determined. Events in which the W decays into a tau and neutrino are used to determine the ratio of the electroweak gauge coupling constants as a measure of lepton universality. Using W and Z decays into electrons, the the W boson mass is measured.
