Description
We propose a model based on $A_4$ modular symmetry in the Inverse seesaw framework to realise light Dirac neutrino mass. This requires extension of SM fermionic sector by three right-handed neutrinos $(ν_R)$, three heavy right-handed fermion field $(S_R)$ and three heavy left-handed fermion field $(S_L)$. The scalar sector of SM is also extended by $SU(2)_L$ singlet ψ. The application of modular symmetry restricts the use of additional flavon fields. The Yukawa couplings are transformed non-trivially under the modular symmetry and it enables the study of neutrino phenomenology with a specific flavor structure of mass matrix. We investigate the phenomenology of neutrino mass and mixing and all are found to be compatible with the observed 3σ limit of current neutrino oscillation data.
