New $[SU(3){]}^4$ Realization of Lepton/Dark Symmetry

Abstract

Extending the well-known $SU(3{)}_C\times SU(3{)}_L\times SU(3{)}_R$ model of quarks and leptons to include a fourth $SU(3{)}_N$ gauge factor, a new realization is obtained, different from leptonic color, which contains a lepton/dark symmetry with the help of an input $Z_4$ symmetry. It is seen to encompass a previous extension of the standard model to $SU(2{)}_N$ lepton symmetry.
