Abstract

We examine the implications of a recently proposed theory of fermion masses and mixings in which an ${A}_{4}$ family symmetry emerges from orbifold compactification. We analyze two variant schemes concerning their predictions for neutrino oscillations, neutrinoless double-beta decay, and the golden quark-lepton unification mass relation. We find that upcoming experiments DUNE as well as LEGEND and nEXO offer good chances of exploring a substantial region of neutrino parameters.

Summary

INTRODUCTION

The discovery of neutrino oscillations [1,2] has prompted a great experimental effort toward precision measurements [3]. Shed light on the possible nature of the family symmetry in four dimensions. In this context, six-dimensional theories compactified on a torus have been suggested [12,13] and a realistic standard model extension has recently been proposed [14] in which fermions are nicely arranged within the framework of an A4 family symmetry. In this work we focus on the possibility of probing the implications of this theory within the generation of neutrino experiments This includes the long-baseline Deep Underground Neutrino Experiment (DUNE) [20,21], as well as neutrinoless double-beta decay (0νββ for short) searches. III we determine the potential of upcoming neutrino experiments, such as DUNE and 0νββ experiments to probe our orbifold compactification predictions
