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.

In this paper, recent experimental results on W and Z boson production at the Tevatron are described. These results not only provide tests of the standard model, but are also sensitive to proton parton distribution functions.

We present recent results on measurements of the transverse momentum distribution of W and Z bosons, the angular distribution of electrons from W decays, and on color coherence effects in W+jets events from p{bar p} collisions at (square root)s = 1.8 TeV at the Fermilab Tevatron Collider. The data are compared to perturbative QCD calculations.

The CDF and D0 experiments at the Tevatron have used p{bar p} collisions at (square root)s = 1.96 TeV to measure the cross section of W and Z boson production using several leptonic final states. An indirect measurement of the total W width has been extracted, and the lepton charge asymmetry in Drell-Yan production has been studied up to invariant masses of 600 GeV/c2.

An overview of W and Z production in high energy hadron collisions is given. W and Z cross section and asymmetry measurements from CDF and D0 are described, with particular emphasis on recent results. The current status of precision W mass and width measurements is reported. The fundamental physics parameters that can be extracted from these measurements are described, and the relevance of W and Z production studies for the LHC is pointed out.

We report on a measurement of the fraction of events with a W or Z boson produced diffractively in {bar p}p collisions at √s = 1.96 TeV, using data from 0.6 fb−1 of integrated luminosity collected with the CDF II detector equipped with a Roman-pot spectrometer that detects the {bar p} from {bar p} + p → {bar p}+[X+W/Z]. We find that (0.97 ± 0.11)% of Ws and (0.85 ± 0.22)% of Zs are produced diffractively in a region of (anti)proton fractional momentum loss [zeta] of 0.03
