Abstract: We present an analysis of data from p ($) over bar p collisions at a center-of-mass energy of root s = 1800 GeV. A measurement is made of the ratio R = sigma B(p ($) over bar p –> W –> ev)/sigma B(p ($) over bar p –> Z(0) –> ee). The data represent 19.6 pb(-1) collected by the Collider Detector at Fermilab during the 1992-1993 collider run of the Fermilab Tevatron. We find R = 10.90 +/- 0.32(stat)+/-0.29(syst), and from this value we extract a measurement of the W –> ev branching ratio Gamma(W –> ev)/Gamma(W) = 0.1094+/-0.0033(stat)+/-0.0031(syst). From this branching ratio we set a limit on the top quark mass of mt > 62 GeV/c(2) at the 95% confidence level. In contrast with direct searches for the top quark, this limit makes no assumptions about the allowed decay modes of the top quark. In addition, we use a calculation of the leptonic width Gamma(W –> ev) to obtain a value for the W total decay width:Gamma(W) = 2.064+/-0.060(stat)+/-0.059(syst) GeV.
