Measurements of inclusive W and Z cross sections in pp collisions at s?=7 TeV

Abstract: Measurements of inclusive W and Z boson production cross sections in pp collisions at s?=7s=7 TeV are presented, based on 2.9 pb?1 of data recorded by the CMS detector at the LHC. The measurements, performed in the electron and muon decay channels, are combined to give ?(pp?WX)×B(W???)=9.95±0.07(stat.)±0.28(syst.)±1.09?(pp?WX)×B(W???)=9.95±0.07(stat.)±0.28(syst.)±1.09 (lumi.) nb and ?(pp?ZX)×B(Z??+??)=0.931±0.026(stat.)±0.023(syst.)±0.102?(pp?ZX)×B(Z??+??)=0.931±0.026(stat.)±0.023(syst.)±0.102 (lumi.) nb, where ? stands for either e or ?. Theoretical predictions, calculated at the next-to-next-to-leading order in QCD using recent parton distribution functions, are in agreement with the measured cross sections. Ratios of cross sections, which incur an experimental systematic uncertainty of less than 4%, are also reported.
