Sažetak
A measurement of total and fiducial inclusive W and Z boson production cross sections in pp collisions at s√=8  TeV is presented. Electron and muon final states are analyzed in a data sample collected with the CMS detector corresponding to an integrated luminosity of 18.2±0.5  pb−1. The measured total inclusive cross sections times branching fractions are σ(pp→WX)×B(W→ℓν)=12.21±0.03(stat)±0.24(syst) ±0.32(lum)  nb and σ(pp→ZX)×B(Z→ℓ+ℓ −)=1.15±0.01(stat)±0.02(syst)±0.03(lum)  nb for the dilepton mass in the range of 60—120 GeV. The measured values agree with next-to-next-to- leading-order QCD cross section calculations. Ratios of cross sections are reported with a precision of 2%. This is the first measurement of inclusive W and Z boson production in proton- proton collisions at s√=8  TeV.
