abstract

  • An analysis of high-transverse-momentum electrons using data from the Collider Detector at Fermilab (CDF) of pp collisions at s=1800 GeV yields values of the production cross section times branching ratio for W and Z0 bosons of (ppWXeX)=2.190.04(stat)0.21(syst) nb and (p»pZ0Xe+e-X)=0.2090.013(stat)0. 017(syst) nb. Detailed descriptions of the CDF electron identification, background, efficiency, and acceptance are included. Theoretical predictions of the cross sections that include a mass for the top quark larger than the W mass, current values of the W and Z0 masses, and higher-order QCD corrections are in good agreement with these measured values. © 1991 The American Physical Society.
