The status of a search for flavor changing neutral current (FCNC) involving a top quark and a Higgs boson decaying into two photons will be presented. The study is based on the CMS experiment in LHC with proton-proton collision at √s = 13 TeV. Especially, the analysis work with the full Run-II data, around the luminosity of 137 fb-1, is ongoing and the limits on branching ratios are expected to be up to the order of 10–3 which is predicted by some BSM models. As a consequence, some predictions from new physics models can be tested at the current stage.
