Predicting CP violation in Deviation from Tri-bimaximal mixing of Neutrinos

Understand

We study the CP violation in the deviation from the tri-bimaximal mixing (TBM) of neutrinos.

• We examine non-trivial relations among the mixing angles and the CP violating Dirac phase in the typical four cases of the deviation from the TBM.
• The first two cases are derived by the additional rotation of the 2-3 or 1-3 generations of neutrinos in the TBM basis.
• The other two cases are given by the additional rotation of the 1-3 or 1-2 generations of charged leptons with the TBM neutrinos.
