# $A_4$ flavor symmetric model in SUSY SU(5) GUT

## TL;DR

This paper introduces an $A_4$ flavor symmetric model within SUSY SU(5) GUT that successfully reproduces observed quark and lepton masses, mixings, and neutrino oscillation data through specific Higgs and scalar field configurations.

## Contribution

It presents a novel $A_4$ flavor symmetry implementation in SUSY SU(5) GUT that accurately models fermion masses and mixings, including recent neutrino oscillation results.

## Key findings

- Successfully reproduces quark and charged lepton masses at GUT scale
- Achieves realistic quark mixing angles consistent with experiments
- Models neutrino masses and oscillations in agreement with data

## Abstract

We propose a model with $A_4$ flavor symmetry for leptons and quarks in the framework of supersymmetric SU(5) grand unified theory (GUT). The running masses of quarks and charged leptons at GUT scale ($\sim 10^{16}$ GeV) are realized by the adjoint 24-dimensional Higgs multiplet and additional gauge singlet scalar fields including flavons. In this paper, we focus on a result of the quark and charged lepton masses and quark mixing since our present model is known to reproduce recent experimental results of the neutrino mass and oscillation. Those results are showed numerically.
