abstract

  • An analysis of proton-antiproton collisions at s =1.8 TeV recorded with the Collider Detector at Fermilab (CDF) yields (ppWX) B(W)=2.210.22 nb and (ppZX)B(Z +-)=0.2260.032 nb. The ratio is R= WB(W)/ZB(Z+-)=9.81.2. Combining with previous CDF electron results gives WB(Wl)=2. 200.20 nb, ZB(Zl+l-)=0.2140.023 nb, and Rl=10.00.8. We extract the ratios of the coupling constants g/ge and g/g. Using standard model assumptions we deduce the inverse branching ratio B-1(Wl), the width (W), and a decay-mode-independent lower bound on the top quark mass of 45 GeV/c2 (95% C.L.). 1992 The American Physical Society.
