Study for vector boson production in association with heavy-flavor jets in proton-proton collisions

The kinematic properties of vector bosons decaying into two opposite-sign same-flavor leptons and heavy-flavor jets that originate from heavy flavor quarks have been studied using proton-proton collisions at the Large Hadron Collider with the CMS experiment at different centre of mass energies. Vector boson + heavy flavor-jets are originated in p-p collisions from gluon-gluon, quark-quark and quark-anti-quark interactions. This study is important to test pQCD theory by comparing experimental cross sections with theoretical predictions and to distinguish signal from the background in many SM processes and BSM searches. The kinematic properties have been compared with the predictions from several Monte Carlo event generators using different parton shower simulations.
