Abstract

We study the discovery potential for a light Higgs boson via gg → H_SM-like → hh → bbγγ process at the Large Hadron Collider (LHC). Focusing on the 2-Higgs Doublet Model (2HDM) Type-I, which can accommodate light neutral Higgs states, of O(100) GeV or less in mass, while agreeing with theoretical and up-to-date experimental constraints, we explore the feasibility of a light CP-even Higgs state h via the largely unexplored final state bbγγ at Run-3 of the LHC. We further propose a few Benchmark Points (BPs) for future searches.
