Study of Higgs boson pair production in the $HH\to b\overline{b}\gamma \gamma$ final state with 308 fb${}^{-1}$ of data collected at $\sqrt{s}=$ 13 TeV and 13.6 TeV by the ATLAS experiment

ATLAS Collaboration

A search for Higgs boson pair production in the $b\bar{b}\gamma \gamma$ final state is performed. The proton-proton collision dataset corresponds to an integrated luminosity of 308 fb$^{-1}…
