Inverse seesaw in A5′ modular symmetry

We make an investigation of modular $\Gamma^{\prime}_5 \simeq A^{\prime}_5$ group in inverse seesaw framework. Modular symmetry is advantageous because it reduces the usage extra scalar fields significantly. Moreover, Yukawa couplings are expressed terms Dedekind eta functions, which also have a $q$ expansion form, utilized to achieve numerical simplicity. Our proposed model includes six heavy fermion superfields i.e., $\mathcal{N}_{Ri}$, $\mathcal{S}_{Li}$ and weighton. The study neutrino phenomenology becomes simplified effective by $A^\prime_5$ symmetry, provides us well defined mass structure for lepton sector. Here, we observe that all oscillation parameters, as electron neutrinoless double beta decay can be accommodated this model. briefly discuss flavor violating decays $\ell_i \to \ell_j \gamma$ comment on non-unitarity mixing matrix.
