Investigating the 95 GeV Higgs boson excesses within the type-I ( 1 + 2 ) HDM
Abstract
In this work, we explore how the 2-Higgs doublet model (2HDM) type-I, extended by an inert doublet, can provide an explanation for the recently observed excesses at the Large Hadron Collider (LHC) in the γ γ and τ + τ − final states. Hence, by imposing theoretical constraints and experimental bounds on the model parameter space, our findings show that a light C P -even Higgs boson, h , with a mass around 95 GeV, can account for these anomalies. This result aligns with the excess in b b ¯ signatures reported in earlier data from the Large Electron-Positron (LEP) collider.
