We report a measurement of the forward-backward charge asymmetry of electrons from W boson decays in p (p) over bar collisions at root of s = 1.96 TeV using a data sample of 170 pb(-1) collected by the Collider Detector at Fermilab. The asymmetry is measured as a function of electron rapidity and transverse energy and provides new input on the momentum fraction dependence of the u and d quark parton distribution functions within the proton.

Abstract

We report a measurement of the forward-backward charge asymmetry of electrons from W boson decays in p (p) over bar collisions at root of s = 1.96 TeV using a data sample of 170 pb(-1) collected by the Collider Detector at Fermilab. The asymmetry is measured as a function of electron rapidity and transverse energy and provides new input on the momentum fraction dependence of the u and d quark parton distribution functions within the proton.
