Higgs boson decays into narrow di-photon jets and their search strategies at the Large Hadron Collider
Abstract
In many extensions of the Standard Model the Higgs boson can decay into two light scalars each of which then subsequently decay into two photons. The underlying event is h 4γ, but the kinematics from boosted light scalar decays combined with realistic detector resolutions may fail to register the events in straightforward categories and thus may be lost. In this article we investigate the phase space for highly boosted di-photon events from these exotic Higgs decays and discuss search strategies that aim to capture and label events in this difficult region. In the process we develop a new category, -jets, which identifies with high selectivity highly collimated di-photon decay modes of the Higgs boson.
