Measurements of vector boson with associated jet production with the ATLAS detector

Productions of light and heavy-flavour jets in association with a W or a Z boson in proton-proton collisions are important processes to study QCD in multi-scale environments and the proton parton content. Cross sections, differential in several kinematics variables, have been measured with the ATLAS detector in 7 TeV proton-proton collisions and compared to high-order QCD calculations and Monte Carlo simulations. The production of heavy flavour in association with a W or Z boson is sensitive to parton density functions and the modelling of heavy-quark flavour production mechanisms.
