This is a review paper about neutrino mass and mixing and flavour model building strategies
based on discrete family symmetry. After a pedagogical introduction and overview of the …

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 …

We study lepton mixing patterns which are derived from finite modular groups ΓN, requiring
subgroups Gν and Ge to be preserved in the neutrino and charged lepton sectors …

The current status of our knowledge of the 3-neutrino mixing parameters and of the CP
violation in the lepton sector is summarised. The non-Abelian discrete symmetry approach to …

A bstract In this paper, we incorporate the modular S 4 flavor symmetry into the
supersymmetric version of the minimal type-I seesaw model, in which only two right-handed …

The pattern of lepton mixing can emerge from breaking a flavor symmetry in different ways in
the neutrino and charged lepton Yukawa sectors. In this framework, we derive the model …

A bstract We consider a scenario with three Majorana neutrinos in which a discrete, finite
flavour group G f is combined with a generalized CP transformation. We derive conditions for …

In this paper, we study the implications of the modular A 4 flavor symmetry in constructing a
supersymmetric minimal type-(I+ II) seesaw model, in which only one right-handed neutrino …

Behind the observed pattern of lepton flavor mixing is a partial or approximate μ-τ flavor
symmetry—a milestone on our road to the true origin of neutrino masses and flavor …

The observed pattern of fermion masses and mixing is an outstanding puzzle in particle
physics, generally known as the flavor problem. Over the years, guided by precision neutrino …
