TL;DR

This paper introduces a novel predictive neutrino mass matrix model using A(4) symmetry and the seesaw mechanism, predicting a normal hierarchy and maximal CP violation in neutrino oscillations.

Contribution

It proposes a new neutrino mass matrix model with A(4) symmetry and only two heavy neutral fermions, leading to specific neutrino mass and mixing predictions.

Findings

Predicts a normal hierarchy of neutrino masses

Forecasts maximal CP violation in neutrino oscillations

Provides a realistic example consistent with current data

Abstract

A new and novel idea for a predictive neutrino mass matrix is presented, using the non-Abelian discrete symmetry A(4) and the seesaw mechanism with only two heavy neutral fermion singlets. Given the components of the one necessarily massless neutrino eigenstate, the other two massive states are automatically generated. A realistic example is discussed with predictions of a normal hierarchy of neutrino masses and maximal CP violation.
