Prediction of Ue3 and \cos 2θ_23 from discrete symmetry

Morimitsu Tanimoto

We discuss the question why the mixing is small. The natural answer is in some symmetric limit, in which two large mixings are realized. It is possible to force…

Lepton Flavor Violating Processes in Bi-maximal Texture of Neutrino Mixings

A. Kageyama, S. Kaneko, N. Shimoyama +1

We investigate the lepton flavor violation in the framework of the MSSM with right-handed neutrinos taking the large mixing angle MSW solution in the quasi-degenerate and the inver…

Solar Neutrino Solutions in Non-Abelian Flavor Symmetry

Morimitsu Tanimoto

We have studied the large mixing angle MSW solution for the solar neutrinos in the non-abelian flavor symmetry. We predict the MNS mixing matrix taking account of the symmetry brea…

Zee-type Neutrino Mass Matrix and Bi-Maximal Mixing

M. Matsuda, C. Jarlskog, S. Skadhauge +1

It is shown that the bi-maximal solution is the only possibility to reconcile Zee-type neutrino mass matrix with three flavors to the current atmospheric and solar neutrino experim…

Generation of Neutrino Masses and Mixings in Gauge Theories

M. Tanimoto

I review models which present large flavor mixings of the lepton sector based on the gauge theory.

Prediction of the CP violation in the Phenomenological Quark-Lepton Mass Matrix Approach

M. Fukugita, M. Tanimoto, T. Yanagida

We explore the phenomenological quark-lepton mass matrices, which are devised following the S flavour symmetry principle, yet fully consistent with SU(5) gauge models with the…
