| contents | We investigate a grand unification (GUT) inspired version of the minimal supersymmetric standard model (MSSM)
based on a left-right symmetric $4$-$2$-$2$ gauge group, incorporating Yukawa coupling unification and current
phenomenological constraints. Utilizing a split soft supersymmetry-breaking (SSB) parameter space motivated by
flavor symmetries, we analyze the implications of recent results from ATLAS, CMS, LHCb, and dark matter direct
detection experiments. Our numerical scans, conducted with SARAH and SPheno, identify viable low-energy regions
consistent with third-generation Yukawa unification, the observed Higgs boson mass, dark matter relic density,
and flavor observables such as $B \to X_s γ$, $B_s \to μ^+ μ^-$ and $B_u \to τν_τ$ .
Our findings suggest that while current bounds severely constrain much of the
MSSM-like parameter space, substantial regions remain experimentally viable and testable in the ongoing LHC run
and next-generation dark matter experiments. |
