A bstractIn the framework of the modular symmetry approach to lepton flavour, we consider a class of theories where matter superfields transform in representations of the finite modular group Γ5 ≃ A5. We explicitly construct a basis for the 11 modular forms of weight 2 and level 5. We show how these forms arrange themselves into two triplets and a quintet of A5. We also present multiplets of modular forms of higher weight. Finally, we provide an example of application of our results… 

Type II seesaw models with modular A4 symmetry

We discuss type-II seesaw models adopting modular $A_4$ symmetry in supersymmetric framework. In our approach, the models are classified by the assignment of $A_4$ representations and modular weights

Neutrino mass and mixing with A5 modular symmetry

We present a comprehensive analysis of neutrino mass and lepton mixing in theories with $A_5$ modular symmetry. We construct the weight 2, weight 4 and weight 6 modular forms of level 5 in terms of

Fermion masses and mixing in modular A4 Symmetry

We consider a flavor model based on A4 modular group to account for both lepton and quark parameters (masses and mixing). The inverse seesaw mechanism is considered to produce the light neutrino

Modular A4 symmetry models of neutrinos and charged leptons

Abstract We present a comprehensive analysis of neutrino mass and lepton mixing in theories with A 4 modular symmetry, where the only flavon field is the single modulus field τ, and all masses

Fermion mass hierarchies from modular symmetry

We show how quark and lepton mass hierarchies can be reproduced in the framework of modular symmetry. The mechanism is analogous to the Froggatt-Nielsen (FN) mechanism, but without requiring any

Modular S3 symmetric radiative seesaw model

We propose a one-loop induced radiative seesaw model applying a modular S3 flavor symmetry, which is known as the minimal non-Abelian discrete group. In this scenario, dark matter (DM) candidate is

Linear Seesaw in A 5 ′ Modular Symmetry With Leptogenesis

In this study, we investigate the implication of modular Γ 5 ′ ≃ A 5 ′ symmetry on neutrino oscillation phenomenology in the linear seesaw framework. In order to achieve the well-defined mass

Abstract We combine SO(10) Grand Unified Theories (GUTs) with A4 modular symmetry and present a comprehensive analysis of the resulting quark and lepton mass matrices for all the simplest cases. We

We analyze a modular invariant model of lepton masses, with neutrino masses originating either from the Weinberg operator or from the seesaw. The constraint provided by modular invariance is so
