dc.description.abstractA search is presented for a new scalar resonance, X, decaying to a standard model Higgs boson and another new scalar particle, Y, in the final state where the Higgs boson decays to a b (b) over bar pair, while the Y particle decays to a pair of photons. The search is performed in the mass range 240-1000 GeV for the resonance X, and in the mass range 70-800 GeV for the particle Y, using proton-proton collision data collected by the CMS experiment at root s = 13 TeV, corresponding to an integrated luminosity of 132 fb(-1). In general, the data are found to be compatible with the standard model expectation. Observed (expected) upper limits at 95% confidence level on the product of the production cross section and the relevant branching fraction are extracted for the X -> YH process, and are found to be within the range of 0.05-2.69 (0.08-1.94) fb, depending on m(X) and m(Y). The most significant deviation from the background-only hypothesis is observed for X and Y masses of 300 and 77 GeV, respectively, with a local (global) significance of 3.33 (0.65) standard deviations.
