The T7 flavor symmetry in 3-3-1 model with neutral leptons
We construct a 3-3-1 model based on non-Abelian discrete symmetry
responsible for the fermion masses. Neutrinos get masses from only anti-sextets
which are in triplets and under . The
flavor mixing patterns and mass splitting are obtained without perturbation.
The tribimaximal form obtained with the breaking in
charged lepton sector and both and must be taken place in neutrino sector but only apart in
breakings (without contribution of
\si'), and the upper bound on neutrino mass at the level is
presented. The Dirac CP violation phase is predicted to either
or which is maximal CP violation. From the
Dirac CP violation phase we obtain the relation between Euler's angles which is
consistent with the experimental in PDG 2012. On the other hand, the realistic
lepton mixing can be obtained if both the direction for breakings and are taken place in
neutrino sectors. The CKM matrix is the identity matrix at the tree-level.Comment: 39 pages, 16 figures. arXiv admin note: substantial text overlap with
