W Production Charge Asymmetry
Public CDF Webpage
We present a direct measurement of the W production charge asymmetry using an integrated luminosity of 1 fb-1. We use a new analysis method which directly reconstructs the W rapidity. We consider two possible W rapidity solutions because of the unknown longitudinal momentum of the neutrino from the W decay. We determine the relative contribution of the event to the two solutions according to the V-A decay structure of the weak interaction and the dependence of W boson rapidity upon the differential cross-section, d(&sigmaW)/dy.
