Probing the Majorana nature of the neutrino with neutrinoless double beta decay

TL;DR

This paper explores how neutrinoless double beta decay can reveal whether neutrinos are Majorana particles, focusing on models with tri-bimaximal mixing like A4 and S4.

Contribution

It analyzes the theoretical implications of NDBD for specific flavor symmetry models, providing insights into their compatibility with Majorana neutrino nature.

Findings

NDBD can test Majorana neutrino hypotheses in these models

Tri-bimaximal mixing models have distinct signatures in NDBD

Theoretical constraints on models from NDBD data

Abstract

Neutrinoless double beta decay (NDBD) is the only experiment that could probe the Majorana nature of the neutrino. Here we study the theoretical implications of NDBD for models yielding tri-bimaximal lepton mixing like A4 and S4.
