Abstract |
We study the decay of a heavy CP-even neutral Higgs into an on-shell Standard Model-like Higgs boson and two photons, H -> h gamma gamma, in the two-Higgs doublet model. We argue that the decay channel H -> h gamma gamma, followed by the decay of the Standard Model Higgs h -> bb, could be observed at the 5 sigma level at the High-Luminosity LHC for masses of the heavy Higgs up to 950 GeV for the type-II, 650 GeV for the Lepton Specific and the Flipped 2HDMs, and 350 GeV for the type-I. We also discuss the possible role of the decay H -> h gamma gamma in discriminating among different types of 2HDMs and in enhancing the total number of events in the final state H -> bb gamma gamma compared to the cascade decay H -> hh followed by h -> gamma gamma h -> bb with identical final state (although with different kinematical distributions). |
