Measurements of rare decays of the Higgs boson, such as H->J/ψγ and H->γ*/Zγ, would enhance our understanding of the standard model (SM) of particle physics , and allow us to probe exotic couplings introduced by possible extensions of the SM. The decay width can be modified by the theories involving heavy fermions, gauge bosons or charged scalars. In the search for rare decays, the leptonic channel is most promising as it has relatively low background and fully reconstructed by CMS detector. This talk covers the analysis with the data collected by CMS detector with 35.9fb-1 data to show the first results of Higgs to llγ in 13TeV.
