DOWNLOAD EBOOKWe present results from W and Z boson production in proton-antiproton collisions at √s = 1.8 TeV using the CDF detector. We measure the W and Z cross sections times lepton branching ratio, [sigma](p{bar p} → W)·B(W → l[nu]{sub l}) and [sigma](p {bar p} → Z)· B(Z → k+l−) l = e, [mu]. We also measure the ratio: R{sub l} = [sigma] · B(W → l[nu]{sub l})/[sigma] · B(Z → ll). From R{sub l}, we extract the W electron and muon branching ratios, BR(W → l[nu]{sub l}, and the total W width, [Gamma]{sub W}. In addition, high transverse mass W →e[nu]{sub e}, candidates provide an alternate, direct measurement of [Gamma]{sub W}.

DOWNLOAD EBOOKThe 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.
