Stability of the next-to-tribimaximal mixings under radiative corrections with the variation of SUSY breaking scale in MSSM

TL;DR

This paper investigates how the next-to-tribimaximal neutrino mixing patterns in the MSSM model are affected by radiative corrections as the SUSY breaking scale varies, considering different neutrino mass orderings and model parameters.

Contribution

It provides a detailed analysis of the stability of NTBM patterns under radiative corrections in MSSM across different SUSY scales and neutrino mass orderings, which was not thoroughly explored before.

Findings

NO is more stable than IO for NTBM patterns.

Radiative corrections stay within 3σ of global fit data at low tanβ.

Neutrino parameters are sensitive to SUSY scale variations.

Abstract

We analyse the radiative stability of the next-to-tribimaximal mixings ($NTBM$) 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 $M_R = 10^{15}$ GeV and two different values of $\tan \beta$. All the neutrino oscillation parameters receive varying radiative corrections irrespective of the $m_S$ values at the electroweak scale, which are all within $3\sigma$ range of the latest global fit data at low value of $\tan \beta$ (30). NO is found to be more stable than IO for all four different NTBM mixing patterns.
