We present a measurement of sigma B(W --> e nu) and sigma B(Z(0) --> e(+)e(-)) in proton-antiproton collisions at root 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. We find sigma B(W --> e nu) = 2.49 +/- 0.12 nb and sigma B(Z(0) --> e(+)e(-)) = 0.231 +/- 0.012 nb.

Abstract
We present a measurement of sigma B(W --> e nu) and sigma B(Z(0) --> e(+)e(-)) in proton-antiproton collisions at root 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. We find sigma B(W --> e nu) = 2.49 +/- 0.12 nb and sigma B(Z(0) --> e(+)e(-)) = 0.231 +/- 0.012 nb.File in questo prodotto:
