| 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-leadingorder 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 ffiffiffi s |
