B. Abbott et al., Measurement of W and Z boson production cross sections in p(p)over-bar collisions at root s=1.8 TeV - art. no. 052003, PHYS REV D, 6005(5), 1999, pp. 2003
D0 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 cros
s sections, multiplied by their leptonic branching fractions, for productio
n in <p(p)over bar> collisions at root s = 1.8 TeV are sigma(W)B(W-->e nu)
= 2.36+/-0.02+/-0.08+/-0.13 nb, sigma(W)B(W-->mu nu) = 2.09+/-0.06+/-0.22+/
-0.11 nb, sigma(Z)B(Z-->e(+)e(-)) = 0.218+/-0.008+/-0.008+/-0.012 nb, and s
igma(Z)B(Z -->mu(+)mu(-)) = 0.178+/-0.022+/-0.021+/-0.009 nb, where the fir
st uncertainty is statistical and the second systematic; the third reflects
the uncertainty in the integrated luminosity. For the combined electron an
d muon analyses, we find sigma(W)B(W-->l nu)/sigma(Z)B(Z-->l(+)l(-)) = 10.9
0+/-0.52. Assuming standard model couplings, we use this result to determin
e the width of the W boson, and obtain Gamma(W) = 2.044+/-0.097 GeV. [S0556
