| Özet |
| A measurement of inclusive W and Z production cross sections in pp collisions at 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)×= 10.31±0.02 (stat.)±0.09 (syst.)±0.10 (th.)±0.41 (lumi.) nb and σ (pp→ ZX)×= 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)×/(σ (pp→ ZX)×= 10.54±0.07 (stat.)±0.08 (syst.)±0.16 (th.) and (σ (pp→ W+ X)×/(σ (pp→ W− X)×= 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 … |
