Nonzero Theta13 for Neutrino Mixing in a Supersymmetric B-L Gauge Model with T_7 Lepton Flavor Symmetry

TL;DR

This paper presents a supersymmetric B-L gauge model incorporating T_7 symmetry that successfully explains a nonzero  in neutrino mixing, predicts correlations among mixing angles, and relates to neutrinoless double beta decay.

Contribution

It introduces a novel supersymmetric B-L gauge model with T_7 symmetry that accounts for nonzero  and predicts specific correlations among neutrino mixing parameters.

Findings

Predicts a correlation between  and 3.

Provides a relation between  and neutrinoless double beta decay effective mass.

Demonstrates compatibility with observed neutrino mixing data.

Abstract

We discuss how \theta_{13} \neq 0 is accommodated in a recently proposed renormalizable model of neutrino mixing using the non-Abelian discrete symmetry T_7 in the context of a supersymmetric extension of the Standard Model with gauged U(1)_{B-L}. We predict a correlation between \theta_{13} and \theta_{23}, as well as the effective neutrino mass m_{ee} in neutrinoless double beta decay.
