摘要

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(→bb¯)H(→γγ), 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 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 ≤ 1000 GeV and 15 ≤ m ≤ 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(→bb¯)H(→γγ) at 13 TeV, ranging from 9 fb to 0.06 fb.
