Precision measurements of W and Z boson production at ATLAS

Precision measurements of the production cross-sections of W/Z boson at LHC provide important tests of perturbative QCD and information about the parton distribution functions for quarks within the proton. In this talk, we present a variety of measurements that probe the production of weak bosons in proton-proton collisions at a variety of collision energies. For inclusive production of W and Z bosons, we present, W+, W− and Z boson cross sections at 2.76 TeV as well as precision measurements of the kinematic properties of Drell-Yan lepton pairs produced at a centre-of-mass energy of 13 TeV. In addition, we present recent measurements of Z production in association with hadronic jets at 8TeV as well as the production of Z bosons in association with heavy flavour jets at 13TeV. All of the measurements are corrected for detector inefficiency and resolution and compared with state-of-the-art theoretical calculations.
