This is a review article about neutrino mass and mixing and flavour model building
strategies based on modular symmetry. After a brief survey of 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 possibility to generate the quark mass hierarchies as well as the CKM
quark mixing and CP violation without fine-tuning in a quark flavour model with modular A 4 …

A bstract In modular-invariant models of flavour, hierarchical fermion mass matrices may
arise solely due to the proximity of the modulus τ to a point of residual symmetry. This …

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 …

Modular flavor symmetries provide us with a very compelling approach to the flavor problem.
It has been argued that moduli values close to some special values like τ= i or τ= ω provide …

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 propose new classes of inflation models based on the modular symmetry, where the
modulus field τ serves as the inflaton. We establish a connection between modular inflation …

We investigate the possibility to describe the quark mass hierarchies as well as the CKM
quark mixing matrix without fine-tuning in a quark flavour model with modular A 4 symmetry …
