Abstract

Tri-bimaximal mixing (TBM) in the neutrino sector has been obtained in constrained sequential dominance where the Yukawa couplings of righ-handed neutrinos have some particular structure. Current neutrino oscillation data suggests that neutrino mixing should deviate from TBM mixing pattern. To explain it, we propose a phenomenological model by adding some small complex parameters to the Yukawa couplings of CSD. Using this we have shown that neutrino mixing angles can deviate from their TBM values. We justify the modified form of Yukawa couplings of our work by constructing a model based on flavor symmetry. © 2022 Institute of Physics Publishing. All rights reserved.
