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

Measurement of W and Z production cross-sections in p{bar p} collisions at {radical}s = 1.8 TeV The cross sections for W and Z production in p{bar p} collisions at {radical}s = 1.8 TeV are measured using the D0 detector at the Fermilab Tevatron collider. The detected final states are W {yields} ev{sub e}, Z {yields} e{sup +}e{sup {minus}}, W {yields} {mu}v{sub {mu}}, and Z {yields} {mu}{sup +}{mu}{sup {minus}}. In the ratio of these measurements, many common sources of systematic error cancel and we measure R = {sigma},(p{bar p} {yields} W) {center_dot} Br(W {yields} lv)/ {sigma},(p{bar p} {yields} Z) {center_dot} Br(Z {yields} l{sup +}l{sup {minus}}). Assuming standard model couplings, this result is used to determine the width of the W bosom and to set a limit on the decay W{sup +} {yields} t{bar b}.
