Neutrino Mass and Flavour Models

TL;DR

This paper reviews recent advances in understanding neutrino mass and mixing, emphasizing models with discrete symmetries and their implications for fermion masses, unification, and solving flavor and CP issues.

Contribution

It provides a comprehensive survey of models with discrete family symmetry, highlighting their potential to explain neutrino properties and related flavor problems.

Findings

Models with discrete symmetries can naturally produce tri-bimaximal mixing.

Recent measurements of a non-zero reactor angle have significant theoretical implications.

Discrete symmetry models can address SUSY flavor and CP problems.

Abstract

We survey some of the recent promising developments in the search for the theory behind neutrino mass and tri-bimaximal mixing, and indeed all fermion masses and mixing. We focus in particular on models with discrete family symmetry and unification, and show how such models can also solve the SUSY flavour and CP problems. We also discuss the theoretical implications of the measurement of a non-zero reactor angle, as hinted at by recent experimental measurements.
