Investigating the 95 GeV Higgs Boson Excesses within the I(1+2)HDM

Investigating the 95 GeV Higgs Boson Excesses within the I(1+2)HDM
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 γγ and τ+τ− final states. Hence, by imposing theoretical constraints and experimental bounds on the model parameter space, our findings show that a light CP-even Higgs boson, h, with a mass around 95 GeV, can account for these anomalies. This result aligns with the excess in bb¯ signatures reported in earlier data from the Large Electron-Positron (LEP) collider.

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 γγ and τ+τ− final states. Hence, by imposing theoretical constraints and experimental bounds on the model parameter space, our findings show that a light CP-even Higgs boson, h, with a mass around 95 GeV, can account for these anomalies. This result aligns with the excess in bb¯ signatures reported in earlier data from the Large Electron-Positron (LEP) collider.
