A general classification of flavor symmetries is provided according to their interplay with the proper Poincaré and gauge groups and to their linear or nonlinear action in field space. The focus is on the lepton sector, and the different types of symmetries describing neutrino masses and the lepton mixing matrix are reviewed. Several illustrative examples are presented for each type of symmetry, and specific strengths and limitations are discussed.

Abstract
A general classification of flavor symmetries is provided according to their interplay with the proper Poincaré and gauge groups and to their linear or nonlinear action in field space. The focus is on the lepton sector, and the different types of symmetries describing neutrino masses and the lepton mixing matrix are reviewed. Several illustrative examples are presented for each type of symmetry, and specific strengths and limitations are discussed.File in questo prodotto:
