According to recent research from Hsinchu, Taiwan, "We investigate the Friedberg-Lee (FL) symmetry and its promotion to include the mu-tau symmetry, and call this 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 S (3) permutation family symmetry. The breaking terms, which are twisted FL symmetric, are introduced," wrote T. Araki and colleagues.
The researchers concluded: "Some viable models in each ...
