A Measurement of $$\sigma\cdot (W\to e \nu)$$ and $$\sigma\cdot (Z^0\to e^+e^-)$$ in $$p\bar{p}$$ collisions at $$\sqrt{s}$$ = 1800 GeV
- Chicago U.
An analysis of high transverse momentum electrons using data from the Collider Detector at Fermilab in $$\bar{p}p$$ collisions at $$\sqrt{s} = 1800$$ GeV yields values of the production cross section times branching ratio for $$W$$ and $Z^0$ bosons of $$\sigma(W\to e \nu)$$ = 2.19 ± 0.04 (stat) ± 0.21 (sys) nb and $$\sigma(Z^0\to e^+e^-)$$ = 0.209 ± 0.013 (stat) ± 0.017 (sys) nb. Detailed descriptions ofthe 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 $Z^0$ masses, and higher order QCD corrections are now in good agreement with these measured values.
