A4A4 Family Symmetry from SU(5)SU(5) SUSY GUTs in 6d

This model is the first which combines the idea of orbifold GUTs with A4 Family Symmetry resulting from the orbifolding.

Abstract

We propose a model in which A4 Family Symmetry arises dynamically from a six-dimensional orbifold SU(5) Supersymmetric Grand Unified Theory. The SU(5) is broken to the Standard Model gauge group by a particular orbifold compactification leading to A4 Family Symmetry, low energy Supersymmetry and Higgs doublet–triplet splitting. The resulting four-dimensional effective superpotential leads to a realistic description of quark and lepton masses and mixing angles including tri-bimaximal neutrino mixing and an inter-family mass hierarchy provided by a Froggatt–Nielsen mechanism. This model is the first which combines the idea of orbifold GUTs with A4 Family Symmetry resulting from the orbifolding.
