Neutrino masses along with fermion mass hierarchy

TL;DR

This paper extends a recent fermion mass hierarchy model to include neutrino masses and mixing, predicting new phenomenology and addressing the fermion mass hierarchy problem in the Standard Model.

Contribution

It generalizes a new fermion mass hierarchy mechanism to incorporate neutrino masses and leptonic mixing, introducing right-handed neutrinos.

Findings

Neutrino masses are generated via the extended model.

Leptonic mixing patterns are obtained.

Predictions for Higgs boson phenomenology are discussed.

Abstract

Recently a new mechanism has been proposed to cure the problem of fermion mass hierarchy in the Standard Model (SM) model. In this scenario, all SM charged fermions other than top quark arise from higher dimensional operators involving the SM Higgs field. This model also predicted some interesting phenomenology of the Higgs boson. We generalize this model to accommodate neutrino masses (Dirac & Majorana) and also obtain the mixing pattern in the leptonic sector. To generate neutrino masses, we add extra three right handed neutrinos $(N_{iR})$ in this model.
