Flavor unification in SU(8)

Abstract

Flavor unification is proposed in the SU(8) gauge group. This model imbeds the Georgi-Glashow SUgg(5) as a subgroup. It is necessary to modify Georgi's second postulate for grand unification so that the left-handed fermion representations are complex with respect to SUc(3)×SUW(2)×UY(1) ×UJ(1). There are three families of light quarks, one right-handed isospin-singlet quark with charge -13 three ordinary lepton families, and one lepton doublet without a right-handed partner. © 1983 The American Physical Society.
