Note About the Implementation of Finite Symmetries in the Lepton Sector

Abstract

Assuming that the leptonic mixing matrix is given in first approximation by the tribimaximal form or a generalization of this, we deduce some consequences with regard to the finite symmetries that may be applied in the minimal lepton sector of the electroweak theory.

T7flavor symmetry scheme for understanding neutrino mass and mixing in 3-3-1 model with neutral leptons

“…The neutrino mass and mixing is one of the most important evidence of beyond Standard Model physics and also one of the biggest challenges in particle physics. Many experiments show that neutrinos have tiny masses and their mixing is sill mysterious [1][2][3][4][5][6][7]. The tri-bimaximal form for explaining the lepton mixing scheme was first proposed by Harrison-Perkins-Scott (HPS), which apart from the phase redefinitions, is given by [8][9][10][11] …”
