Measurement of W and Z boson production in association with jets at ATLAS

Measurements of W/Z-boson production in association with jets are an important test of perturbative QCD prediction and also yield information about the parton distribution functions of the proton. Cross sections for Z-boson production in association with heavy-flavour jets will be presented as well as differential measurements of these events at high transverse momentum. We will also present results on collinear Z+jet production. The data are compared to theoretical predictions provided by various Monte Carlo event generators.
