Effects of variations of SUSY breaking scale on neutrino parameters at low energy scale under radiative corrections

TL;DR

This study investigates how changing the SUSY breaking scale between 2 and 14 TeV influences neutrino masses and mixings through radiative corrections, using both bottom-up and top-down RGEs approaches.

Contribution

It provides a detailed analysis of the impact of SUSY breaking scale variations on neutrino parameters, incorporating a self-complementarity relation and dual RGE approaches.

Findings

Significant radiative correction effects on neutrino parameters due to SUSY scale variation.

Both normal and inverted neutrino mass hierarchies are analyzed.

The study extends previous work by exploring a wider SUSY breaking scale range.

Abstract

The paper addresses the effects of the variations of the SUSY breaking scale $m_s$ in the range (2-14) TeV on the three neutrino masses and mixings, in running the renormalization group equations (RGEs) for different input values of high energy seesaw scale $M_R$, in both normal and inverted hierarchical neutrino mass models. The present investigation is a continuation of the earlier works based on the variation of $m_s$ scale. Two approaches are adopted one after another - bottom-up approach for running gauge and Yukawa couplings from low to high energy scale, followed by the top-down approach from high to low energy scale for running neutrino parameters defined at high energy scale, along with gauge and Yukawa couplings. A self-complementarity relation among three mixing angles is also employed in the analysis. Significant effect due to radiative corrections on neutrino parameters with the variation of SUSY breaking scale $m_s$, is observed.
