Abstract (data abstract)
This paper presents a measurement of the production cross-section of a $Z$ boson in association with $b$- and $c$-jets, in proton-proton collisions at $ \sqrt{s} = 13$ TeV with the ATLAS experiment at the Large Hadron Collider using data corresponding to an integrated luminosity of 140 fb$^{-1}$, i.e. full Run 2 statistics. Inclusive and differential cross-sections are measured for events containing a $Z$ boson decaying into electrons or muons and produced in association with at least one $b$- or $c$-jets or at least two $b$-jets with transverse momentum $p_T > 20$ Ge and rapidity $|y|<2.5$. Predictions from several Monte Carlo generators based on leading-order (LO) or next-to-leading-order (NLO) matrix elements interfaced with a parton-shower simulation and testing different flavour schemes for the choice of initial-state partons are compared with measured cross-sections alongside innovative fixed order with next-to-next-to-leading-order precision predictions with IRC safe algorithms. N.B.: Data correspond to average of electron and muon channel.
