$B_s^0 \rightarrow μ^+ μ^-$ in a flavor violating extension of MSSM
$B$ meson rare decays play a crucial role in exploring new physics beyond the standard model. In this study, we explore the rare decay process $B_s^0 \rightarrow μ^+ μ^-$ in a flavor violating extension of the Minimal Supersymmetric Standard Model (MSSM), namely the $μ$-from-$ν$ SSM ($μν$SSM). Combined with the decay $\bar{B}\rightarrow X_sγ$, the numerical results indicate that the $μν$SSM can successfully accommodate the experimental data for $B_s^0 \rightarrow μ^+ μ^-$ and additionally narrow down the parameter space.
