Description

We present results from W and Z boson production in proton-antiproton collisions at {radical}s = 1.8 TeV using the CDF detector. We measure the W and Z cross sections times lepton branching ratio, {sigma}(p{bar p} {yields} W){center_dot}B(W {yields} l{nu}{sub l}) and {sigma}(p {bar p} {yields} Z){center_dot} B(Z {yields} k{sup +}l{sup {minus}}) l = e, {mu}. We also measure the ratio: R{sub l} = {sigma} {center_dot} B(W {yields} l{nu}{sub l})/{sigma} {center_dot} B(Z {yields} ll). From R{sub l}, we extract the W electron and muon branching ratios, BR(W {yields} l{nu}{sub l}, and the total W width, {Gamma}{sub W}. In addition, high transverse … continued below
