| contents | This paper presents the first dedicated study of the boosted $HH \to b\bar{b}γγ$ topology as a key probe of physics beyond the Standard Model (SM) in the high-energy double-Higgs boson regime. The analysis presented in this paper, focuses on two classes of new-physics scenarios: non-resonant deviations of the quartic gauge--Higgs interaction, parameterized by the coupling modifier $κ_{2V}$, and resonant enhancement arising from the decay of a heavy scalar state, modeled within a two-Higgs-doublet framework. We demonstrate that the boosted reconstruction category enhances sensitivity to beyond SM effects that populate the high-$m_{HH}$ tail, yielding improved constraints on $κ_{2V}$ and extending the discovery reach for heavy resonances. |
