Measurement of the forward-backward charge asymmetry from W→ev production in pp̄ collisions at √s=1.96 TeV

TL;DR: In this article, the forward-backward charge asymmetry of electrons from W boson decays in pp collisions at √s=1.96 TeV using a data sample of 170 pb-1 collected by the Collider Detector at Fermilab.

Abstract: We report a measurement of the forward-backward charge asymmetry of electrons from W boson decays in pp 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. © 2005 The American Physical Society.
