The Unique Horizontal Symmetry of Leptons
Sep, 2008Citations per year
Abstract: (arXiv)
There is a group-theoretical connection between fermion mixing matrices and minimal horizontal symmetry groups. Applying this connection to the tri-bimaximal neutrino mixing matrix, we show that the minimal horizontal symmetry group for leptons is uniquely S4, the permutation group of four objects.- 14.60.Pq
