Hunting light Higgses at the LHC in the context of the 2HDM Type-I
Hunting light Higgses at the LHC in the context of the 2HDM Type-I
We show the reinterpretation of existing searches for exotic decays of the Standard Model (SM)-like Higgs, H→aa(hh), in various final states, in the framework of the 2-Higgs Doublet Model (2HDM) Type-I. We then explore a new search for such light Higgses, a and h, at the Large Hadron Collider (LHC) Run 3 for an integrated luminosity of 300 fb−1. After performing a scan over the model parameters, we found that the inverted scenario of Type-I offers a new promising signal in the form of the following cascade decays: H→Z∗a→Z∗Z∗h→bb¯¯μ−μ+jj. We investigate then its significance through a full Monte Carlo (MC) simulation down to the detector level.

Abstract
We show the reinterpretation of existing searches for exotic decays of the Standard Model (SM)-like Higgs, H→aa(hh), in various final states, in the framework of the 2-Higgs Doublet Model (2HDM) Type-I. We then explore a new search for such light Higgses, a and h, at the Large Hadron Collider (LHC) Run 3 for an integrated luminosity of 300 fb−1. After performing a scan over the model parameters, we found that the inverted scenario of Type-I offers a new promising signal in the form of the following cascade decays: H→Z∗a→Z∗Z∗h→bb¯¯μ−μ+jj. We investigate then its significance through a full Monte Carlo (MC) simulation down to the detector level.
