Search for a resonance decaying into a scalar particle and a Higgs boson in the final state with two bottom quarks and two photons with 199 fb${}^{-1}$ of data collected at $\sqrt{s}$=13 and 13.6 TeV with the ATLAS detector

ATLAS Collaboration

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 \rightarrow S (\rightarrow b \bar{b})H ( \ri…
