Abstract
Measurements of fiducial integrated and differential cross sections for inclusive W+, W− and Z boson production are reported. They are based on 25.0 ± 0.5 pb−1 of pp collision data at √ s = 5.02 TeV collected with the ATLAS detector at the CERN Large Hadron Collider. Electron and muon decay channels are analysed, and the combined W+, W− and Z integrated cross sections are found to be σW+ = 2266 ± 9 (stat) ± 29 (syst) ± 43 (lumi) pb, σW− = 1401 ± 7 (stat) ± 18 (syst) ± 27 (lumi) pb, and σZ = 374.5±3.4 (stat)±3.6 (syst)±7.0 (lumi) pb, in good agreement with next-to-next-to-leading-order QCD crosssection calculations.Thesemeasurements serve as references for Pb+Pb interactions at the LHC at √ sNN = 5.02 TeV.| File | Dimensione | Formato | |
