Abstract

DØ has measured the inclusive production cross section of W and Z bosons in a sample of 13 pb−1 of data collected at the Fermilab Tevatron. The cross sections, multiplied by their leptonic branching fractions, for production in p¯p collisions at √s=1.8 TeV are σWB(−→Weν)=2.36±0.02±0.08±0.13nb, σWB(−→Wμν)=2.09±0.06±0.22±0.11nb, σZB(→Ze+e−)=0.218±0.008±0.008±0.012nb, and σZB(→Zμ+μ−)=0.178±0.022±0.021±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 σWB(−→Wlν)/σZB(→Zl+l−)=10.90±0.52. Assuming standard model couplings, we use this result to determine the width of the W boson, and obtain Γ(W)=2.044±0.097GeV.
