Measurements of vector bosons plus jets production with the ATLAS detector

The production of jets in association with vector bosons in proton-proton collisions at the LHC provide unique tool to study various QCD and EW effects. Measurements of jets produced in association with a Z boson can be used to study electroweak vector boson fusion mechanism. Measurements of vectors bosons in association with heavy flavor, such as W+c and W+b production, have unique sensitivity to the heavy quark density of the proton. Differential cross sections are presented and compared to QCD predictions at NLO and NNLO.
