DO/ has measured the inclusive production cross section of [ital W] and [ital Z] bosons in a sample of 13 pb[sup [minus]1] of data collected at the Fermilab Tevatron. The cross sections, multiplied by their leptonic branching fractions, for production in p[bar p] collisions at [radical] (s) =1.8 TeV are [sigma][sub W] B(W[r arrow]e [nu])=2.36 [plus minus] 0.02 [plus minus] 0.08 [plus minus] 0.13nb, [sigma] [sub W] B(W[r arrow][mu][nu])=2.09 [plus minus] 0.06 [plus minus] 0.22 [plus minus] 0.11nb, [sigma] [sub Z] B(Z[r arrow]e [sup +] e [sup [minus]])=0.218[plus minus] 0.008 [plus minus] 0.008 [plus minus] 0.012nb, and [sigma] [sub Z] B(Z[r arrow][mu] [sup +] [mu] [sup [minus]])=0.178 [plus minus] 0.022 [plus minus] 0.021[plus minus] 0.009nb, where the first uncertainty is statistical and the second systematic; the third reflects the uncertainty in the integrated luminosity. For the combined electron and muon analyses, we find [sigma] [sub W] B(W[r arrow] l [nu])/[sigma] [sub Z] B(Z[r arrow]l [sup +]l [sup [minus]])=10.90 [plus minus] 0.52. Assuming standard model couplings, we use this result to determine the width of the [ital W] boson, and obtain [Gamma] (W)=2.044 [plus minus] 0.097 GeV.
