[Talk will not happen live, recording to be uploaded on Friday]
The study of the associated production of vector bosons and jets constitutes an excellent enviroment to check numerous QCD predictions. Total and differential cross sections of vector bosons produced in association with jets have been studied in pp collisions using CMS data. Differential distributions as function of a broad range of kinematical observables are measured and compared with theoretical predictions. The talk will discuss both inclusive jet analyses, and analyses targeting heavy flavor production.
