Neutrino properties in E6×SU(2)F supersymmetric GUT with spontaneous CP violation
Abstract
We examined the neutrino sector in E6×SU(2)F supersymmetric grand unified theory with spontaneous CP violation. At first glance, the discrete symmetry, which is introduced in order to solve the supersymmetric CP problem, constrains the allowed operators too strongly for the neutrino sector to be consistent with the experimental data, i.e., the μ neutrino becomes massless as commented in the previous paper. We showed that this issue can be solved if some operators are taken into account. And we saw that such operators do not play an important role in studying quark and charged lepton sectors. The predictions on the neutrino masses and mixings are the same as the E6 models, which are consistent with various experiments on the neutrino oscillations.
