要旨:
We discuss flavor symmetries in left-right symmetric theories. We show that
such frameworks are a different environment for flavor symmetry model building
compared to the usually considered cases. This does not only concern the need
to obey the enlarged gauge structure, but also more subtle issues with respect
to residual symmetries. Furthermore, if the discrete left-right symmetry is
charge conjugation, potential inconsistencies between the flavor and charge
conjugation symmetries should be taken care of. In our predictive model based
on A4 we analyze the correlations between the smallest neutrino mass, the
atmospheric mixing angle and the Dirac CP phase, the latter prefers to lie
around maximal values. There is no lepton flavor violation from the Higgs
bi-doublet.
