Tri-Bimaximal Mixing from Twisted Friedberg-Lee Symmetry
Abstract
We investigate the Friedberg-Lee (FL) symmetry and its promotion to include the μ - τ symmetry, and call that the twisted FL symmetry.Based on the twisted FL symmetry, two possible schemes are presented toward the realistic neutrino mass spectrum and the tri-bimaximal mixing.In the first scheme, we suggest the semi-uniform translation of the FL symmetry.The second one is based on the S3 permutation family symmetry.The breaking terms, which are twisted FL symmetric, are introduced.Some viable models in each scheme are also presented.
