Abstract
The SUSY-EW one-loop quantum contributions to flavor-changing MSSM Higgs-boson decays into $b\overline{s}$ and $s\overline{b}$ are computed and discussed. We use the full diagrammatic approach that is valid for all $\mathrm{tan}\ensuremath{\beta}$ values and do not rely on the mass-insertion approximation for the characteristic flavor-changing parameter. We analyze in full detail the dependence of these flavor-changing partial widths on all the relevant MSSM parameters and also study the nondecoupling behavior of these widths with the SUSY mass parameters. We find that these contributions are sizable as compared to the SM ones, and together with the SUSY-QCD contributions they can be very efficient as an indirect method in the future search for supersymmetry.
