Abstract

The inclusive cross sections times leptonic branching ratios for

W

and

Z

boson production in

p \bar{p}

collisions at

\sqrt{s} = 1.8

TeV were measured using the D0 detector at the Fermilab Tevatron collider:

σ_{W} B (W \to e ν) = 2.36 \pm 0.07 \pm 0.13 nb

σ_{W} B (W \to μ ν) = 2.09 \pm 0.23 \pm 0.11 nb

σ_{Z} B (Z \to e^{+} e^{-}) = 0.218 \pm 0.011 \pm 0.012 nb

, and

σ_{Z} B (Z \to μ^{+} μ^{-}) = 0.178 \pm 0.030 \pm 0.009 nb

. The first error is the combined statistical and systematic uncertainty, and the second reflects the uncertainty in the luminosity. For the combined electron and muon analyses we find

σ_{W} B (W \to l ν) / σ_{Z} B (Z \to l^{+} l^{-}) = 10.90 \pm 0.49

. Assuming standard model couplings, this result is used to determine the width of the

W

boson,

γ (W) = 2.044 \pm 0.093 GeV
