Hexagonal SU(3) Unification and its Manifestation at the TeV Scale

Abstract

We consider $SU(3{)}_C\times SU(2{)}_{AL}\times SU(2{)}_{BL}\times U(1{)}_Y$ as the low-energy subgroup of supersymmetric $SU(3{)}^6$ unification. This may imply small deviations from quark-lepton universality at the TeV scale, as allowed by neutron-decay data. New particles are predicted with specific properties. We discuss in particular the new heavy gauge bosons corresponding to $SU(2{)}_{AL}\times SU(2{)}_{BL}\to SU(2{)}_L$.
