Sažetak
A measurement of inclusive W and Z production cross sections in pp collisions at s=7 TeV is presented. The electron and muon decay channels are analyzed in a data sample collected with the CMS detector at the LHC and corresponding to an integrated luminosity of 36 pb−1. The measured inclusive cross sections are σ(pp → WX) × W  = 10.31 ± 0.02 (stat.) ± 0.09 (syst.) ± 0.10 (th.) ±  0.41 (lumi.) nb and σ(pp → ZX) × Z+−  = 0.974 ± 0.007 (stat.) ±  0.007 (syst.) ± 0.018 (th.) ± 0.039 (lumi.) nb, limited to the dilepton invariant mass range 60 to 120 GeV. The luminosity- independent cross section ratios are (σ(pp → WX) × W /(σ(pp → ZX)  × Z+−  = 10.54 ± 0.07 (stat.) ± 0.08 (syst.) ± 0.16 (th.) and (σ(pp  → W+ X) × W++ /(σ(pp → W− X) × W−−  = 1.421 ± 0.006 (stat.) ±  0.014 (syst.) ± 0.029 (th.). The measured values agree with next- to-next-to-leading order QCD cross section calculations based on recent parton distribution functions.
