The magnetic field in the nucleus is calculated microscopically. It is deduced that Salam and Strathdee's theory will unlikely provide an explanation for anomalies in the Fermi coupling constants in 35Arand 93Nb. CP violation in the β-decays of n and 19Neis not ruled out.

We study the CP violation in the deviation from the tri-bimaximal (TBM) mixing of neutrinos. We examine nontrivial 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. These four cases predict different relations among three mixing angles and the CP violating Dirac phase. The rotation of the 2-3 generations of neutrinos in the TBM basis predicts sin2θ12< 1/3, and the CP violating Dirac phase to be ±(0.09π–0.76π) for NH (±(0.15π–0.73π) for IH) depending on sin2θ23. The rotation of the 1-3 generations of neutrinos in the TBM basis gives sin2θ12> 1/3. The CP violating Dirac phase is not constrained by the input of the present experimental data. For the case of the 1-3 and 1-2 rotations of charged leptons in the TBM basis, the CP violating Dirac phase is predicted in ±(0.35π–0.60π) depending on sin2θ12for both normal hierarchy (NH) and inverted hierarchy (IH) cases. We also discuss the specific case that θ13is related with the Cabibbo angle λ such as [Formula: see text], in which the maximal CP violation is preferred. The CP violating Dirac phase can distinguish the lepton flavor mixing patterns at T2K and NOνA experiments in the future.
