Generation of non-zero $θ_{13}$ in broken $A_4$ neutrino mass model    [PDF]

Manikanta Borah, Bikash Sharma, Mrinal Kumar Das
Stability of neutrino masses and mixings with non-zero $\theta_{13}$ is an important issue in recent neutrino physics. In context of this, a detail analysis on two-fold degenerate $(m_1=m_2, m_3)$ neutrino mass model is done with Renormaization Group Equation (RGE) in Minimal Supersymmetric Standard Model (MSSM). Considering the input values of neutrino masses and mixing angles at high scale predictions are studied at low energy scale using RGE. We have also found that two-fold degenerate model with $\theta_{13}=0$ can produce consistent results at low energy with non-zero $\theta_{13}$ from the breaking of a generic $A_4$ model.
