Searches of Higgs boson rare decays

Recent results on searches for rare decays of the Higgs boson, obtained using 35.9~$\mathrm{fb}^{-1}$ of ${\textrm{proton-proton}}$ collision data collected at ${\sqrt{s} = 13~\mathrm{TeV}}$ with the CMS detector, are presented. This report includes searches for the Higgs boson decaying into invisible particles, muon pairs, ${\mathrm{J}/\psi\,\gamma}$ and ${\mathrm{Z}\gamma}$ final states. No significant deviations from the standard model predictions have been observed and upper limits are placed on the corresponding decay branching fractions.
