Abstract

We report a measurement of the forward-backward charge asymmetry of electrons from W boson decays in pp̅ collisions at √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.
