Tri-bimaximal and bimaximal neutrino mixing from discrete symmetries

TL;DR

This paper reviews how discrete symmetries can produce tri-bimaximal and bimaximal neutrino mixing patterns, which effectively explain neutrino oscillation data, and provides an explicit example of such a model.

Contribution

It introduces explicit models based on discrete symmetries that realize tri-bimaximal and bimaximal neutrino mixing patterns.

Findings

Tri-bimaximal mixing explains neutrino oscillation data well.

Bimaximal mixing is also a viable starting point for lepton mixing models.

Explicit models demonstrate how discrete symmetries lead to these mixing patterns.

Abstract

The neutrino oscillation data are well explained by the tri-bimaximal pattern. Recently it has been shown that also the bimaximal pattern could be a very good starting point in order to describe the lepton mixing. In this paper I review both the flavour structures and then I present an explicit example.
