Study of vector boson + heavy flavour jets production in the CMS experiment

by Krisztina Márton (Wigner FK RMI NFO), Endre Bokor (student at Imperial 
College London (UK), NKFIH - UK GYAK fellowship), Viktor Veszprémi (Wigner 
FK)

The production of vector boson in association with heavy flavour jets is an 
important process in hadron colliders. It provides high-accuracy tests of the 
standard model, can be used to improve Monte Carlo generators, and has an 
important role in Higgs precision measurements and in new physics searches. In 
our analysis, we are studying events with a Z boson decayed to a pair of muons 
or electrons, and 2 jets originating from b quarks or from c quarks, to measure 
the Z+bb / Z+cc cross section ratio. In this presentation, we are going to 
focus on the object and event selection used in this analysis, show control 
plots about basic kinematic quantities of the leptons and jets, and compare 
them with the recently published CMS analysis on Z+b production.
