TL;DR

This paper analyzes the predictions of a supersymmetric SO(10) model with $S_4 \times Z_n$ flavor symmetry for lepton flavor violation, incorporating full two-loop RG effects and assessing experimental discovery prospects.

Contribution

It provides a detailed numerical analysis of LFV processes in a specific SUSY GUT model with flavor symmetry, including full RG effects and experimental implications.

Findings

Projected sensitivity of LFV experiments like MEG-II to the model.

Regions of parameter space already excluded by LHC searches.

Potential for future tests at HL-LHC and next-generation experiments.

Abstract

The heavy right-handed neutrinos in supersymmetric models can act as the source of lepton flavor violation (LFV). LFV processes like $ \mu \rightarrow e \gamma $, $ \tau \rightarrow \mu \gamma $, $ \tau \rightarrow e \gamma $ is an effective way to explore new physics beyond the SM. Among the possible processes, $ \mu $ decays have the greatest discovery potential in most of the supersymmetric models. Experimental inference of lepton flavor-violating processes within a supersymmetric type-II seesaw framework in the non-universal Higgs model (NUHM) and non-universal Scalar Mass model for Yukawa mixing scenarios in the $ S_{4} $ theory with an additional discrete symmetry is presented. The numerical analysis includes full 2 loop renormalization group running effects for the the above mentioned Yukawa coupling matrices. The projected discovery reach of LFV experiments (MEG-II) is mentioned and those regions in mSUGRA, NUHM, NUSM models that have already been excluded by the LHC searches or that which is probed by MEG experiments is specified here. The results presented in this work can influence experimental challenges and physics motivations to construct various BSM theories and sensitivity to test these theories at next run of HE/HL LHC is also considered.
