TL;DR

This paper explores how finite symmetries can be implemented in the minimal lepton sector, assuming the tribimaximal mixing matrix as a first approximation, to understand their implications for leptonic mixing.

Contribution

It investigates the application of finite symmetries in the lepton sector based on the tribimaximal mixing assumption, providing insights into symmetry constraints.

Findings

Finite symmetries can be consistent with tribimaximal mixing

Constraints on symmetry groups for leptonic mixing

Implications for model building in lepton sector

Abstract

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