Stability of neutrino oscillation parameters at low energy scale with the variations of SUSY breaking scale under Renormalisation Group Equations

TL;DR

This paper analyzes how neutrino oscillation parameters and self-complementarity relations remain stable at low energy scales despite variations in the SUSY breaking scale, with implications for neutrino mass observables.

Contribution

It investigates the stability of neutrino oscillation parameters and self-complementarity relations under radiative corrections with varying SUSY breaking scales in both hierarchical cases.

Findings

Neutrino parameters remain stable within 1σ at electroweak scale.

Normal hierarchy shows greater stability than inverted hierarchy.

Neutrino mass observables stay below current observational bounds.

Abstract

We discuss the stability of the neutrino oscillation parameters at low energy scale including self-complementarity (SC) relations among mixing angles under radiative corrections with the variation of SUSY breaking scale ($m_s$) in both normal and inverted hierarchical cases. We observe that the neutrino oscillation parameters including the SC relation maintains stability at the electroweak scale within $1\sigma$ range of the latest global fit data. NH case maintains more stability than IH case. All the numerical values related to the absolute neutrino masses viz., $\Sigma |m_i|$, $m_{\beta}$ and $m_{ \beta \beta}$ are found to lie below the observational upper bound.
