Measurement of the Forward-Backward Charge Asymmetry from W --> e nu Production in p anti-p Collisions at s**(1/2) = 1.96 TeV

Abstract

We report a measurement of the forward-backward charge asymmetry of electrons from W boson decays in p anti-p collisions at s**(1/2) = 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 within the proton.
