Measurement of the Ratio σB(W→eν)σB(Z0→e+e-) in p¯p Collisions at s=1.8 TeV Academic Article uri icon


  • We present a measurement of the ratio σB(W→eν)σB(Z0→e+e-) in p̄p 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 σB(W→eν)σB(Z0→e+e-)=10.90±0.32(stat)±0. 29(syst). From this value, we extract a value for the W width, Γ(W)=2.064±0.061(stat)±0.059(syst) GeV, and the branching ratio, Γ(W→eν)Γ(W)=0.1094±0.0033(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.
