Neutrino Mixing in Unified Extended Seesaw Model

TL;DR

This paper explores a unified extended seesaw model with family symmetry, demonstrating its ability to produce realistic fermion masses and leptonic mixing patterns close to tri-bimaximal mixing.

Contribution

It introduces a novel unified model incorporating extended seesaw and family symmetry to achieve viable fermion masses and realistic leptonic mixing.

Findings

Leptonic mixing is close to tri-bimaximal.

The model successfully generates realistic fermion masses.

Extended seesaw mechanism is effective in the unified framework.

Abstract

The seesaw mechanism can play a key role in the generation of the leptonic mixing in unified models. We consider an unified model with a family symmetry and extended seesaw, and obtain viable fermion masses and mixing (leptonic mixing is close to tri-bi-maximal).
