Title: Measurement of the ratio {sigma}{ital B}({ital p{bar p}}{r_arrow}{ital W}{r_arrow}{ital e}{nu})/{sigma}{ital B}({ital p{bar p}}{r_arrow}{ital Z}{sup 0}{r_arrow}{ital ee}) in {ital p{bar p}} collisions at {radical}{ital s} =1800 GeV

Abstract

We present an analysis of data from {ital p} {bar p} collisions at a center-of-mass energy of {radical}{ital s} =1800 GeV. A measurement is made of the ratio {ital R}{equivalent_to}{sigma}{ital B}({ital p} {ital {bar p}}{r_arrow}{ital W}{r_arrow}{ital e}{nu})/{sigma}{ital B}({ital p} {bar p}{r_arrow}{ital Z}{sup 0}{r_arrow}{ital ee}). The data represent 19.6 pg{sup {minus}1} collected by the Collider Detector at Fermilab during the 1992--1993 collider run of the Fermilab Tevatron. We find {ital R}=10.90{plus_minus}0.32(stat){plus_minus}0.29(syst), and from this value we extract a measurement of the {ital W}{r_arrow}{ital e}{nu} branching ratio {Gamma}({ital W}{r_arrow}{ital e}{nu})/{Gamma}({ital W})=0.1094{plus_minus}0.0033(stat){plus_minus}0.0031(syst). From this branching ratio we set a limit on the top quark mass of {ital m}{sub {ital t}}{gt}62 GeV/{ital c}{sup 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}({ital W}{r_arrow}{ital e}{nu}) to obtain a value for the {ital W} total decay width: {Gamma}({ital W})=2.064{plus_minus}0.060(stat){plus_minus}0.059(syst) GeV.
