A new solution of the fermionic mass hierarchy of the standard model

TL;DR

This paper introduces a minimal symmetry-based mechanism to explain the fermionic mass hierarchy and neutrino mixing in the standard model, addressing phenomenological constraints from kaon mixing.

Contribution

It proposes a novel symmetry approach using Z_2 imes Z_5 to unify the explanation of fermion masses, mixing, and neutrino parameters.

Findings

The mechanism successfully reproduces fermion mass hierarchies.

Constraints from kaon mixing are derived for the model.

The approach explains neutrino masses and mixing parameters.

Abstract

We present a new mechanism for solving the fermionic masses and mixing hierarchies of the standard model through a minimal symmetry $\mathcal{Z}_2 \times \mathcal{Z}_5$. The mechanism is also capable of explaining the neutrino masses and mixing parameters. The phenomenological bounds arising from kaon mixing are also derived on the parameter space of the model.
