Abstract

An analysis of W and Z boson production at UA1, using 4.66 pb^-1 of data from the 1988 and 1989 CERN pp Collider runs at s=0.63 TeV, yields R≡σ_WBr(W→μv)/σ_zBr (Z→μμ)=10.4_-1.5^+1.8stat.± 0.8(syst.) We find R=9.5_-1.0^+1.1(stat.+syst.) when combining all available UA1 data, in both the electron and muon channel, taken in the period 1983-1989. In the framework of the standard model, the value of R is used to infer the total width of the W boson, Γ_W^tot=2.18_-0.24^+0.26 (exp.)±0.04(theory) GeV/c².
