Description
Results from search for the rare decays of the standard model\,(SM) Higgs and Z boson to a J/$\Psi$ or $\Psi'$ meson and a photon, with subsequent decay of the meson to a pair of muons will be presented in this contribution. The analysis is performed using data recorded by the CMS detector during full Run 2 from proton-proton collisions at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 123 $fb^{-1}$. No excess of events has been observed over the SM background. Upper limit at $95\%$ confidence level are set on the branching fractions of these decay channels.
