Description: 
'Ratios of cross sections, $\sigma(Z+c~jets)/\sigma(Z+jets)$, $\sigma(Z+b~jets)/\sigma(Z+jets)$ and $\sigma(Z+c~jets)/\sigma(Z+b~jets)$  in the associated production of a Z boson with at least one charm or bottom quark jet are measured in proton-proton collisions at $\sqrt{s}=13$ TeV. The data sample, collected by the CMS experiment at the CERN LHC, corresponds to an integrated luminosity of 35.9 $fv^{-1}$, with a fiducial volume of $p_T > 30 $ GeV and $|\eta|<2.4$ for the jets. The Z boson candidates come from leptonic decays into electrons or muons with $p_T > 25 $ GeV and $|\eta|<2.4$  and the dilepton mass satisfies $ 71 < M_Z < 111 $ GeV.'
