We present a study on the possibility of observing a hypothetical particle known as the Flavon HF, which is predicted in an extension of the standard model that includes the so-called Froggatt-Nielsen mechanism. The proposed decay channel is through a bbh final state, where the Higgs boson (h) decays to a pair of photons or a pair of b quarks (h→ γγ, bb). We found that, under special scenarios of the model parameter space, the processes analyzed could provide evidence for the existence of the Flavon in the next stage of the LHC: the High Luminosity LHC. Specifically, we predict a signal significance of 5σ (2σ) in the h→ bb (h→γγ) channel for a Flavon mass of 800 (900) GeV and an integrated luminosity of 2500 (3000) fb-1.
