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(*> 𝑏𝑏b^-)𝐻(*> *g*g), 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&sup(−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 *{ 𝑚𝑋 *{ 1000 GeV and 15 *{ 𝑚𝑆 *{ 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(*> 𝑏𝑏b^-)𝐻(*> *g*g) at 13 TeV, ranging from 9 fb to 0.06 fb.
