Abstract

We analyse the radiative stability of the next-to-tribimaximal mixings ( $N T B M$ ) with the variation of SUSY breaking scale ( $m_{S}$ ) in MSSM, for both normal ordering (NO) and inverted ordering (IO) at the fixed input value of seesaw scale $M_{R} = 1 0^{15}$ GeV and two different values of $tan β$ . All the neutrino oscillation parameters receive varying radiative corrections irrespective of the $m_{S}$ values at the electroweak scale, which are all within $3 σ$ range of the latest global fit data at low value of $tan β$ (30). NO is found to be more stable than IO for all four different NTBM mixing patterns.
