Review of W and Z Production at the Tevatron
Cecilia E. Gerber
Abstract
The CDF and 0 collaborations have used recent data taken at the Tevatron to perform QCD tests with W and Z bosons decaying leptonically. 0 measures the production cross section times branching ratio for W and Z bosons. This also gives an indirect measurement of the total width of the W boson: =2.1260.092 GeV. CDF reports on a direct measurement of =2.190.19 GeV, in good agreement with the indirect determination and Standard Model predictions. 0's measurement of the differential dσ/dpT distribution for W and Z bosons decaying to electrons agrees with the combined QCD perturbative and resummation calculations. In addition, the dσ/dpT distribution for the Z boson discriminates between different vector boson production models. Studies of W+ Jet production at CDF find the NLO QCD prediction for the production rate of W+1 Jet events to be in good agreement with the data.
