Measurement of inclusive W and Z boson production cross sections in pp collisions at s= 13 TeV
Abstract: A measurement of total inclusive and fiducial W and Z boson production cross sections in pp collisions at 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 ± 2 pb1. The measured total inclusive cross sections times branching fractions are σ(ppW+X)×B(W++ν)= 11370 ± 50 (stat) ± 230 (syst) ± 550 (lumi) pb, σ(ppWX)×B(Wˉν)= 8580 ± 50 (stat) ± 160 (syst) ± 410 (lumi) pb, and σ(ppZX)×B(Z+)= 1910 ± 10 (stat) ± 40 (syst) ± 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.
