New Flavor U(1)_F Symmetry for SUSY SU(5)
arXiv:1109.2642 · doi:10.1016/j.physletb.2011.11.052
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.
