QCD in W/Z boson + jets events

Measurements of weak boson production in association with jets are presented. First, differential cross sections for Z-boson and W-boson production in association with jets are presented, with the measurements performed using proton-proton collisions at √s = 8 TeV. The data are compared to next-to-leading order QCD calculations and predictions from a variety of different parton distribution functions. In addition, if available, differential cross sections are presented for Z-boson production in association with heavy-flavour jets at √s = 13 TeV. The data are compared to theoretical predictions provided by various Monte Carlo event generators.
