About the mixing and CP violation in neutrino system

Suppose the geometrical explaination to the weak CP phase in quark sector is also valid for neutrinos, the mixing and CP violation in neutrino system are discussed. We find a larger Jcp than 3x10-3 implys the large-mixing solution for solar neutrino problem. In case of bi-maximal mixing, we predict relative large CP violation with Jcp larger than 3x10-3 in neutrino system, except the third mixing angle approachs to 0 or Π/2 very closely
