We present the first direct measurement of the W production charge asymmetry as a function of the W boson rapidity yW in pp̅ collisions at sqrt[s]=1.96  TeV. We use a sample of W→eν events in data from 1  fb-1 of integrated luminosity collected using the CDF II detector. In the region |yW|<3.0, this measurement is capable of constraining the ratio of up- and down-quark momentum distributions in the proton more directly than in previous measurements of the asymmetry that are functions of the charged-lepton pseudorapidity.
