Measurement of $$\sigma \cdot B (W \to e \nu)$$ and $$\sigma \cdot B(Z^0 \to e^+e^-)$$ in $$p\bar{p}$$ Collisions at $$\sqrt{s}=1.8$$ TeV

Journal Article · · Phys.Rev.Lett.

We present a measurement of $$\sigma \cdot B(W \rightarrow e \nu)$$ and $$\sigma \cdot B(Z~0 \rightarrow e~+e~-)$$ in proton - antiproton collisions at $$\sqrt{s} =1.8$$ TeV using a significantly improved understanding of the integrated luminosity. The data represent an integrated luminosity of 19.7 pb$$~{-1}$$ from the 1992-1993 run with the Collider Detector at Fermilab (CDF). We find $$\sigma \cdot B(W \rightarrow e \nu) = 2.49 \pm 0.12$$nb and $$\sigma \cdot B(Z~0 \rightarrow e~+e~-) = 0.231 \pm 0.012$$nb.
