Abstract

Theoretically, in order to achieve non-zero θ₁₃ a little deviation from Tribimaximal Mixing (TBM) pattern is needed, especially on θ₁₃ without perturbing the atmospheric and solar mixing angles. In this work we computed the neutrino mixing angles by disturbing the θ₁₃ as well as θ₁₂ in Bimaximal (BM) and Hexagonal mixing (HM) using non-diagonal charged lepton mass. Considering the standard form of mass texture which satisfies TBM we have shown the quasi-degenerate nature of neutrino. This quasi degenerate type of mass matrix for BM and HM is then used to calculate the deviated mixing pattern which are consistent with recent neutrino oscillation data.
