abstract

  • We present a measurement of the ratio B(We)B(Z0e+e-) in pp collisions at 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 B(We)B(Z0e+e-)=10.900.32(stat)0. 29(syst). From this value, we extract a value for the W width, (W)=2.0640.061(stat)0.059(syst) GeV, and the branching ratio, (We)(W)=0.10940.0033(stat)0.0031(syst), and we set a decay-mode-independent limit on the top quark mass mtop>62 GeV/c2 at the 95% C.L. 1994 The American Physical Society.
