Reviving trinification models through an E6 -extended supersymmetric GUT
We present a supersymmetric (SUSY) model based on trinification [SU(3)]3 and family SU(3)F symmetries embedded into a maximal subgroup of E8, where the sectors of light Higgs bosons and leptons are unified into a single chiral supermultiplet. The common origin of gauge trinification and of the family symmetry from E8 separates the model from other trinification-based GUTs, as it protects, in parti
