dc.description.abstractMeasurements of inclusive W and Z boson production cross sections in pp collisions at √s = 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 σ(pp→WX) × B(W→ℓν) = 9.95 ± 0.07 (stat.) ± 0.28 (syst.) ±1.09 (lumi.) nb and σ(pp→ZX) × B(Z→ℓ+ℓ−) = 0.931 ± 0.026 stat.) ± 0.023 (syst.) ± 0.102 (lumi.) nb, where ℓ stands for either e or μ. 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.en_US
