Abstract

Measurements of inclusive W and Z cross sections times leptonic branching ratios for $p\bar p$ collisions at $\sqrt s$=1.96 TeV are reported here on behalf of the CDF and D0 collaborations. The data correspond t an integrated luminosity up to 200 $pb\_-1$. The ratio of leptonic W and Z rates is measured and the leptonic branching fraction $B(W \to \ell\nu)$ is extracted as well as an indirect value for the total width of teh W and the CKM matrix element $|Vcs|$.
