This dissertation describes a direct measurement of the W boson total decay width, {Lambda}{sub W}, using the D0 detector at the Fermilab Tevatron Collider. The measurement uses an integrated luminosity of 177.3 pb{sup -1} data, collected during the 2002-2003 run. The width is determined from the shape of the transverse mass distribution, M{sub T}, by fitting the data in the tail region 100

This dissertation describes a direct measurement of the W boson total decay width, ?W, using the D0 detector at the Fermilab Tevatron Collider. The measurement uses an integrated luminosity of 177.3 pb-1 data, collected during the 2002-2003 run. The width is determined from the shape of the transverse mass distribution, MT, by fitting the data in the tail region 100 MsubT/sub 200 GeV. The result if ?

We 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}.
