We report on a measurement of the mass dependence of the forward-backward charge asymmetry, A(FB), and production cross section d sigma /dM for e(+)e(-) pairs with mass M-ee > 40 GeV/c(2). The data sample consists of 108 pb(-1) of p (p) over bar collisions at roots = 1.8 TeV taken by the Collider Detector at Fermilab during 1992-1995. The measured asymmetry and d sigma /dM are compared with the predictions of the standard model and a model with an extra Z' gauge boson.

Abstract
We report on a measurement of the mass dependence of the forward-backward charge asymmetry, A(FB), and production cross section d sigma /dM for e(+)e(-) pairs with mass M-ee > 40 GeV/c(2). The data sample consists of 108 pb(-1) of p (p) over bar collisions at roots = 1.8 TeV taken by the Collider Detector at Fermilab during 1992-1995. The measured asymmetry and d sigma /dM are compared with the predictions of the standard model and a model with an extra Z' gauge boson.File in questo prodotto:
