Abstract
Measurements of fiducial integrated and differ- ential 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. Elec- tron and muon decay channels are analysed, and the com- bined W+, W− and Z integrated cross sections are found tobeσW+ = 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 cross- section calculations. These measurements serve as references for Pb+Pb interactions at the LHC at √sNN = 5.02 TeV.
