Abstract

This paper presents the first dedicated study of the boosted HH→bb¯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: nonresonant deviations of the quartic gauge-Higgs interaction, parametrized by the coupling modifier κ2V, 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-mHH tail, yielding improved constraints on κ2V and extending the discovery reach for heavy resonances.
