Abstract

We present a measurement of the ratio sigmaB(W --> eupsilon)/sigmaB(Z0 --> e+e-) in ppBAR collisions at square-root s = 1.8 TeV. The data represent an integrated luminosity of 21.7 pb-1 from the 1992-1993 run of the Collider Detector at Fermilab. We find sigmaB(W --> eupsilon)/sigmaB(Z0 --> e+e-) = 10.90 +/- 0.32(stat) +/- 0.29(syst). From this value, we extract a value for the W width, GAMMA(W) = 2.064 +/- 0.061(stat) +/- 0.059(syst) GeV, and the branching ratio, GAMMA(W --> eupsilon)/GAMMA(W) = 0.1094 +/- 0.0033(stat) +/- 0.0031(syst), and we set a decay-mode-independent limit on the top quark mass m(top) > 62 GeV/c2 at the 95% C.L.
