Abstract

Within the framework of the next to minimum B-L supersymmetric model (NB-LSSM), we investigate the flavor transition process $\bar B\rightarrow X_s\gamma$ . Building upon this foundation, we further discuss the Higgs decay process $h \to bs$ under the constraint from the $\bar B\rightarrow X_s\gamma$ process. Our study reveals that the branching ratio of $h \to bs$ can significantly deviate from the Standard Model (SM) expectation, depending on the values of the new parameters introduced in the model. This finding highlights the modulation of new physics parameters on the Higgs flavor-violating decay and provides important theoretical grounds for exploring new physics beyond the SM through flavor observables.
