Universal Inverse seesaw mechanism as a source of the SM fermion mass hierarchy

TL;DR

This paper proposes a renormalizable inverse seesaw model that explains the Standard Model fermion mass hierarchy, neutrino masses, and addresses leptogenesis, dark matter, and magnetic moment anomalies within a unified framework.

Contribution

It introduces the first inverse seesaw implementation for charged fermions, generating their masses at different loop levels, and integrates explanations for neutrino masses, leptogenesis, and dark matter.

Findings

Successfully explains SM fermion mass hierarchy

Generates tiny active neutrino masses at two-loop level

Aligns with experimental constraints on meson oscillations and magnetic moments

Abstract

We build a renormalizable theory where the inverse seesaw mechanism explains the pattern of SM fermion masses. To the best of our knowledge, our model corresponds to the first implementation of the inverse seesaw mechanism for the charged fermion sector. In our theory, the inverse seesaw mechanism is implemented at the tree and one-loop levels in order to generate the masses for the second and first families of the SM charged fermions, respectively. The third family of SM charged fermions obtain tree-level masses from the Higgs doublets $\phi _{1}$ (for the top quark) and $\phi _{2}$ (for the bottom quark and tau lepton). The masses of the active light neutrinos are generated from a two-loop level inverse seesaw mechanism. Our model successfully explains the observed SM fermion mass hierarchy, the tiny masses of the active light neutrinos, contains the necessary means for efficient leptogenesis and is in accordance with the constraints resulting from meson oscillations, as well as with the measured values of the observed dark matter relic density and of the muon and electron anomalous magnetic moments.
