| Özet |
| Measurements of inclusive W and Z boson production cross sections in pp collisions at 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\(\sigma\left ({{\text {pp}}\to {\text {W}} X}\right)\times\mathcal {B}\left ({{\text {W}}\to\ell\nu}\right)= 9.95\pm 0.07\left ({{\text {stat}}{.}}\right)\pm 0.28\left ({{\text {syst}}{.}}\right)\pm 1.09\)(lumi.) nb and\(\sigma\left ({{\text {pp}}\to {\text {Z}} X}\right)\times\mathcal {B}\left ({Z\to {\ell^{+}}{\ell^{-}}}\right)= 0.931\pm 0.026\left ({{\text {stat}}{.}}\right)\pm 0.023\left ({{\text {syst}}{.}}\right)\pm 0.102\)(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 … |
