| November 2015 | ||
| Abstract: A measurement of total inclusive and fiducial W and Z boson production cross sections in pp collisions at $\sqrt{s} =$ 13 TeV is presented. Electron and muon final states are studied in a data sample collected with the CMS detector corresponding to an integrated luminosity of up to 43 $\pm$ 2 pb$^{-1}$. The measured total inclusive cross sections times branching fractions are $ \sigma(\mathrm{p}\mathrm{p} \to \mathrm{W}^+ X) \times \mathcal{B}(\mathrm{W}^+ \to \ell^+\nu) =$ 11370 $\pm$ 50 (stat) $\pm$ 230 (syst) $\pm$ 550 (lumi) pb, $\sigma(\mathrm{p}\mathrm{p} \to \mathrm{W}^- X) \times \mathcal{B}(\mathrm{W}^- \to \ell^-\bar{\nu}) =$ 8580 $\pm$ 50 (stat) $\pm$ 160 (syst) $\pm$ 410 (lumi) pb, and $\sigma(\mathrm{p}\mathrm{p} \to \mathrm{Z} X) \times \mathcal{B}(\mathrm{Z} \to \ell^+\ell^-) =$ 1910 $\pm$ 10 (stat) $\pm$ 40 (syst) $\pm$ 90 (lumi) pb for the dilepton mass in the range of 60 to 120 GeV. The measured values agree with next-to-next-to-leading-order QCD cross section calculations. Inclusive cross sections and ratios of cross sections are reported. | ||

| Summary |
| In summary, a measurement of total inclusive and fiducial W and Z boson production cross sections in pp collisions at $\sqrt{s} =$ 13 TeV is presented. Electron and muon final states are studied in a data sample collected with the CMS detector corresponding to an integrated luminosity of up to 43 $\pm$ 2 pb$^{-1}$. The measured total inclusive cross sections times branching fractions are $ \sigma( \mathrm{ pp \to W^+X }) \times \mathrm{B} ( \mathrm{ W^+ \to \ell^+ \nu }) =$ 11370 $\pm$ 50 (stat) $\pm$ 230 (syst) $\pm$ 550 (lumi) pb, $ \sigma( \mathrm{ pp \to W^- X }) \times \mathrm{B} ( \mathrm{ W^- \to \ell^- \nu }) =$ 8580 $\pm$ 50 (stat) $\pm$ 160 (syst) $\pm$ 410 (lumi) pb, and $ \sigma( \mathrm{ pp \to ZX }) \times \mathrm{B} ( \mathrm{ Z \to \ell^+ \ell^- }) = $ 1910 $\pm$ 10 (stat) $\pm$ 40 (syst) $\pm$ 90 (lumi) pb for the dilepton mass in the range of 60 to 120 GeV. The measured values agree with next-to-next-to-leading-order QCD cross section calculations. Inclusive cross sections and ratios of cross sections are reported. |
