Modular Invariance Model for Lepton Masses and Mixing

A flavor model based on 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 of the modular form. The calculated lepton parameters (masses and m...

Description
Summary:A flavor model based on 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 of the 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.
