Vector boson production in association with jets and heavy flavor quarks from CMS

摘要

This document is dedicated to recent results on the measurements of a vectorboson production associated with jets (V+jets) using CMS detector experiment,with a central proton-proton (pp) collision energy of respectively 8 TeV (RunI)and 13 TeV (RunII). The vector boson can be a W boson, Z boson, orphoton({\gamma}). The jets are of any flavor, as well as the ones containingheavy flavor quarks, such as bottom(b) quarks. The inclusive cross sections ofV+jets processes and differential cross sections as a function of variouskinematic observables are presented and compared to several theoreticalpredictions. In general, the comparison between theoretical calculations andmeasurement are crucial for improving modeling and precision on QCD dynamics.
