Toward minimal renormalizable SUSY SU(5) Grand Unified Model with tribimaximal mixing from A4 Flavor symmetry

TL;DR

This paper proposes a minimal, renormalizable SUSY SU(5) grand unified model incorporating A4 flavor symmetry to naturally produce observed neutrino mixing patterns via the Type II Seesaw mechanism.

Contribution

It introduces a novel minimal SUSY SU(5) GUT model with A4 flavor symmetry that explains fermion masses and tribimaximal neutrino mixing.

Findings

Successfully reproduces neutrino mixing patterns

Integrates A4 flavor symmetry into a renormalizable GUT

Provides a natural explanation for fermion mass hierarchies

Abstract

We address the problem of rationalizing the pattern of fermion masses and mixings by adding a nonabelian flavor symmetry in a grand unified framework. With this purpose, we include an A4 flavor symmetry into a unified renormalizable SUSY GUT SU(5) model. With the help of the "Type II Seesaw" mechanism we are able to obtain the pattern of observed neutrino mixings in a natural way, through the so called tribimaximal matrix.
