This is a review article about neutrino mass and mixing and flavour model building
strategies based on modular symmetry. After an introduction to neutrino mass and lepton …

Abstract The Standard Model lacks an organizing principle to describe quark and lepton
“flavours”. Neutrino oscillation experiments show that leptons mix very differently from …

A bstract We analyse the possibility of describing quark masses, mixing and CP violation
in\({S} _4^{\prime}\) modular flavour models without flavons. We focus on the case where the …

A bstract We study the problem of modulus stabilisation in the framework of the modular
symmetry approach to the flavour problem. By analysing simple UV-motivated CP-invariant …

A bstract We study A 4× A 4× A 4 modular symmetric flavor models to realize quark mass
hierarchies and mixing angles without fine-tuning. Mass matrices are written in terms of …

A bstract Eclectic flavor groups arising from string compactifications combine the power of
modular and traditional flavor symmetries to address the flavor puzzle. This top-down …

We review the modular flavor symmetric models of quarks and leptons focusing on our
works. We present some flavor models of quarks and leptons by using finite modular groups …

We study modular symmetric quark flavor models without fine-tuning. Mass matrices are
written in terms of modular forms, and modular forms in the vicinity of the modular fixed …

A bstract We study a symmetry breaking of residual flavor symmetries realized at fixed points
of the moduli space. In the supersymmetric modular invariant theories, a small departure of …

A bstract The Kähler potentials of modular symmetry models receive unsuppressed
contributions which may be controlled by a flavor symmetry, where the combination of the …
