QCD measurements of vector-boson production with the ATLAS detector

Measurements of W and Z bosons production at the LHC with the ATLAS detector are presented. These measurements include total and differential cross-sections of inclusive vector-boson production as well as in association with jets. The results show sensitivity to the parton distribution functions (PDFs), are used to test predictions from Quantum Chromodynamics (QCD) and to tune Monte Carlo (MC) predictions.
