Název v původním jazyce

Precision measurement and interpretation of inclusive W+ , W- and Z/ γ* production cross sections with the ATLAS detector

Popis výsledku v původním jazyce

High-precision measurements by the ATLAS Collaboration are presented of inclusive W+→ℓ+ν , W−→ℓ−ν¯ and Z/γ∗→ℓℓ ( ℓ=e,μ ) Drell–Yan production cross sections at the LHC. The data were collected in proton–proton collisions at s√=7TeV with an integrated luminosity of 4.6fb−1 . Differential W+ and W− cross sections are measured in a lepton pseudorapidity range |ηℓ|<2.5 . Differential Z/γ∗ cross sections are measured as a function of the absolute dilepton rapidity, for |yℓℓ|<3.6 , for three intervals of dilepton mass, mℓℓ , extending from 46 to 150GeV . The integrated and differential electron- and muon-channel cross sections are combined and compared to theoretical predictions using recent sets of parton distribution functions. The data, together with the final inclusive e±p scattering cross-section data from H1 and ZEUS, are interpreted in a next-to-next-to-leading-order QCD analysis, and a new set of parton distribution functions, ATLAS-epWZ16, is obtained.n
