Abstract
Electroweak unification is obtained in anSU(7) model at a mass scale 3×1010≦M≦3×1016 GeV's, with left-right symmetric subgroups and sin2 θ w (M)=3/8. BelowM, the model reduces toSU(3) L ×SU(3) R , the flavor sector of the “trinification theory” of Glashow et al., or of theE 6 grand unified theory. This model predicts a natural massless neutrino, and fractionally charged leptons with masses in theM regime.
