Quasi two-zero texture in Type-II seesaw at fixed points from modular $A_4$ symmetry

Abstract: We study a quasi two-zero neutrino texture based on type-II seesaw model in a modular $A_4$ symmetry to evade the cosmological bound on the sum of neutrino mass while keeping some predictability in neutrino sector. Working on three fixed points for modulus, we discuss predictions of the model and show the allowed points satisfying the cosmological bound on neutrino mass from both CMB and CMB+BAO data.
