Abstract / Description:The SUSY-EW one-loop quantum contributions to
flavour-changing MSSM Higgs-boson decays into $b \bar s$
and $s \bar b$ are computed and discussed. We use the full
diagrammatic approach that is valid for all $\tan \beta$
values and do not rely on the mass-insertion approximation
for the characteristic flavour-changing parameter. We
analyze in full detail the dependence of these
flavour-changing partial widths on all the relevant MSSM
parameters and also study the non-decoupling behaviour 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.
