A [SU(6)] FLAVOR MODEL WITHOUT MIRROR FERMIONS
We introduce a three family extension of the Pati-Salam model which is
anomaly-free and contains in a single irreducible representation the known
quarks and leptons without mirror fermions. Assuming that the breaking of the
symmetry admits the implementation of the survival hypothesis, we calculate the
mass scales using the renormalization group equation. Finally we show that the
proton remains perturbatively stable.Comment: Z PHYS. C63, 339 (1994
The Generational Seesaw Mechanism in [SU(6)]Z}
In the context of the left-right symmetric gauge group [SU(6)]
Z which unifies nongravitational forces with flavors, we analyze the
generational seesaw mechanism. At tree level we get
mmM/M, m, where
M GeVs and M TeVs is the mass scale at which the
horizontal interactions get spontaneously broken. The right handed neutrinos
get a Majorana mass MM of the order of the scale where SU(2) is
broken. An exotic neutral lepton with a mass of the order of M/M is
predicted. First order radiative corrections will produce m
which is at least two orders of magnitude smaller than the other two neutrino
masses
