Model of Large Mixing Angle MSW Solution

Abstract

We have obtained the neutrino mass matrix with the large mixing angle (LMA) MSW solution, ${\sin }^{2}2{\mathrm{th}}_{\odot }=0.65\sim 0.97$ and $\Delta m_{\odot }^2=10^{-5}\sim 10^{-4}{\text{eV}}^2$, in the $S_{3L}\times S_{3R}$ flavor symmetry. The structure of our neutrino mass matrix is found to be stable against radiative corrections.
