W boson production in association with jets at CMS

The production of a W boson in association with jets provides a stringent test of perturbative QCD and is a background process in searches for new physics. Differential cross section measurements of W bosons produced in association with jets and heavy flavor quarks in proton-proton collisions at center-of-mass energies of 8 TeV and 13 TeV in the CMS experiment at the LHC are presented. The measurements are compared to higher order calculations and event simulations that devise matrix element calculations interfaced with parton showers.
