Neutrino Masses and Deviation from Tri-bimaximal mixing in \Delta(27) model with Inverse Seesaw Mechanism

TL;DR

This paper presents a model combining elta(27) flavor symmetry and inverse seesaw to explain neutrino masses, deviations from tri-bimaximal mixing, and hierarchies in leptons and quarks.

Contribution

It introduces a novel elta(27)-based framework linking lepton number violation to neutrino mixing deviations and mass hierarchies, extending to quark sector.

Findings

Neutrino masses and mixing deviations are successfully modeled.

Hierarchies of charged leptons and quarks are explained.

The model connects lepton number violation to observable neutrino properties.

Abstract

We propose a scheme, based on \Delta(27) flavor symmetry and supplemented by other discrete symmetries and inverse seesaw mechanism, where both the light neutrino masses and the deviation from tri-bimaximal mixing matrix can be linked to the source of lepton number violation. The hierarchies of the charged leptons are explained. We find that the quark masses including their hierarchies and the mixing can also be constructed in a similar way.
