Abstract |
A search for the resonant production of a heavy scalar X decaying into a lighter scalar S and a Higgs boson, through the process X -> S(-> b (b) over bar )H(-> gamma gamma), where the two photons are consistent with the Higgs boson decay, is performed. The search is conducted using integrated luminosities of 140 and 59 fb(-1) of proton-proton collision data at centre-of-mass energies of 13 and 13.6 TeV, respectively, recorded with the ATLAS detector at the LHC. The search is performed over the mass ranges of 170 <= m(X) <= 1000 GeV and 15 <= m(S) <= 500 GeV. No significant excess over the Standard Model background predictions is observed and limits at 95% confidence level are set on the product of cross section and branching fraction for the process X -> S(-> b (b) over bar )H(-> gamma gamma) at 13 TeV, ranging from 9 fb to 0.06 fb. |
