Review of W and Z production at the Tevatron
The CDF and D0 collaborations have used recent data taken at the Tevatron to perform QCD tests with W and Z bosons decaying leptonically. D0 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: {Lambda}{sub W} = 2.126 {+-} 0.092 GeV. CDF reports on a direct measurement of {Lambda}{sub W} = 2.19 {+-} 0.19 GeV, in good agreement with the indirect determination and Standard Model predictions. D0's measurement of the differential d{sigma}/dp{sub T} distribution for W and Z bosons decaying to electrons agrees with the combined QCD perturbative and resummation calculations. In addition, the d{sigma}/dp{sub T} 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 + {ge} 1 Jet events to be in good agreement with the data.
