TL;DR
This paper introduces new anomaly-free U(1)_F flavor symmetries within SUSY SU(5) GUTs, providing models that naturally explain fermion mass hierarchies and mixing angles.
Contribution
It presents three concrete, economical models with anomaly-free U(1)_F symmetries that address fermion mass and mixing hierarchies in SUSY SU(5).
Findings
Models successfully reproduce observed fermion hierarchies
U(1)_F symmetry remains anomaly-free in all scenarios
Provides a framework for phenomenologically interesting model building
Abstract
Within supersymmetric SU(5) Grand Unified Theory, we present several new scenarios with anomaly free flavor symmetry U(1)_F. Within each scenario, a variety of cases offer many possibilities for phenomenologically interesting model building. We present three concrete and economical models with anomaly free U(1)_F leading to natural understanding of observed hierarchies between charged fermion masses and CKM mixing angles.
