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 …

Application of non-Abelian finite groups to the theory of neutrino masses and mixing is
reviewed, which is strongly suggested by the agreement of the tribimaximal (TB) mixing …

We review pedagogically non-Abelian discrete groups, which play an important role in
particle physics. We show group-theoretical aspects for many concrete groups, such as …

Recent data from neutrino experiments gives intriguing hints about the mass ordering, the
CP violating phase and non-maximal atmospheric mixing. There seems to be a (one sigma) …

We present the first example of a grand unified theory (GUT) with a modular symmetry
interpreted as a family symmetry. The theory is based on supersymmetric SU (5) in 6d …

This chapter of the report of the “Flavor in the era of the LHC” Workshop discusses the
theoretical, phenomenological and experimental issues related to flavor phenomena in the …

We build a supersymmetric model of quark and lepton masses based on the discrete flavour
symmetry group T′, the double covering of A4. In the lepton sector our model is practically …

A bstract We propose a renormalisable model based on A 4 family symmetry with an SU (5)
grand unified theory (GUT) which leads to the minimal supersymmetric standard model …

We investigate the possibility of using icosahedral symmetry as a family symmetry group in
the lepton sector. The rotational icosahedral group, which is isomorphic to A 5, the …

Following the recent T2K indication of a sizeable reactor angle, we present a class of
models which fix θ13 while preserving trimaximal solar mixing. The models are based on a …
