Abstract

We report the first measurements of inclusive W and Z cross sections times leptonic branching ratios for pp collisions at √s = 1.96 TeV, based on their decays to electrons and muons. The data correspond to an integrated luminosity of 72 pb-1 recorded with the CDF detector at the Fermilab Tevatron. We test e-μ universality in W decays, and we measure the ratio of leptonic W and Z rates from which the leptonic branching fraction B(W → lν) can be extracted as well as an indirect value for the total width of the W and the Cabibbo-Kobayashi-Maskawa matrix element, |V cs|. © 2005 The American Physical Society.
