Title: Measurement of {ital W} and {ital Z} boson production cross sections in p{bar p} collisions at {radical} (s) =1.8 TeV

Abstract

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. {copyright} {ital 1999} {ital The American Physical Society}
