Abstract. We report the first measurements of inclusive W and Z boson cross-sections times the corresponding leptonic branching ratios for $p\overline{p}$ collisions at $\sqrt{s} = 1.96$ TeV based on the decays of the W and Z bosons into electrons and muons. The data were recorded with the CDF II detector at the Fermilab Tevatron and correspond to an integrated luminosity of 72.0 ± 4.3 pb⁻¹. We test e-μ lepton universality in W decays by measuring the ratio of the W → μν to W → eν cross sections and determine a value of 0.991 ± 0.004(stat.) ± 0.011(syst.) for the ratio of W − ell − ν couplings (g_μ/g_e). Since there is no sign of non-universality, we combine our cross-section measurements in the different lepton decay modes and obtain $\sigma_{W} \times\, {\rm Br} (\ppbar \rightarrow W \rightarrow \ell \nu) = 2.749 \pm 0.010({\rm stat.}) \,\pm\, 0.053({\rm syst.}) \,\pm\, 0.165({\rm lum.})$ nb and $\sigma_{\gamma^{*}/Z} \times\, {\rm Br} (\ppbar \rightarrow \gamma^{*}/Z \rightarrow \ell \ell) = 254.9 \,\pm\, 3.3({\rm stat.}) \,\pm\, 4.6({\rm syst.}) \pm 15.2({\rm lum.})$ pb for dilepton pairs in the mass range between 66 GeV/c² and 116 GeV/c². We compute the ratio R of the W → ell ν to Z → ell ell cross sections taking all correlations among channels into account and obtain R = 10.84 ± 0.15(stat.) ± 0.14(syst.) including a correction for the virtual photon exchange component in our measured γ*/Z → ell ell cross section. Based on the measured value of R, we extract values for the W leptonic branching ratio, Br(W → ell ν)= 0.1082 ± 0.0022; the total width of the W boson, Γ(W)= 2092 ± 42 MeV; and the ratio of W and Z boson total widths, Γ(W)/Γ(Z)= 0.838 ± 0.017. In addition, we use our extracted value of Γ(W) whose value depends on various electroweak parameters and certain CKM matrix elements to constrain the V_cs CKM matrix element, |V_cs| = 0.976 ± 0.030.
