Abstract

A flavor model based on A4 modular group is proposed. We consider the inverse seesaw
mechanism to produce the light neutrino masses. Both neutrino and charged lepton masses are obtained
in terms of Yukawa coupling ratios and the module τ of the A4 modular form. The calculated lepton
parameters (masses and mixings) are in good agreement with the recent neutrino data. The present mixing
pattern can be realized as a consequence of deviation from the bimaximal symmetry.

Keywords

neutrino, modular flavor symmetries, discrete symmetries, particle physics, high energy physics.
