A prediction of neutrino mixing matrix with CP violating phase

Understand

The latest experimental progress have established three kinds of neutrino oscillations with three mixing angles measured to rather high precision.

• There is still one parameter, i.e., the CP violating phase, missing in the neutrino mixing matrix.
• It is shown that a replay between different parametrizations of the mixing matrix can determine the full neutrino mixing matrix together with the CP violating phase.
• From the maximal CP violation observed in the original Kobayashi-Maskawa (KM) scheme of quark mixing matrix, we make an Ansatz of maximal CP violation in the neutrino mixing matrix.
