Measurement of the inclusive W and Z production cross sections in pp collisions at root s = 7 TeV with the CMS experiment
Original language description
A measurement of inclusive W and Z production cross sections in pp collisions at root 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 integratedluminosity of 36 pb(-1). The measured inclusive cross sections are sigma(pp -} WX) x B(W -} lv) = 10.31 +/- 0.02 (stat.) +/- 0.09 (syst.) +/- 0.10 (th.) +/- 0.41 (lumi.) nb and sigma(pp -} ZX) x B(Z -} l(broken vertical bar) l(-)) = 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 (sigma(pp -} WX) x B(W -} lv)) / (sigma(pp -} ZX) x B(Z -} l(+)l(-))) = 10.54 +/-0.07 (stat.) +/- 0.08 (syst.) +/- 0.16 (th.) and (sigma(pp -} W(+) X) x B(W(+) -} l(+) v)) / (sigma(pp -} W(-) X) x B(W(-) -} l(-) (v) over bar)) = 1.421 +/- 0.006 (stat.) +/- 0.014 (syst.) +/- 0.029 (th.). The measured values agree with
