Abstract / Description:Flavour changing effects originating from the exchange of scalar particles in the processes e^{+} e^{-} -> H b \bar{s}, H \bar{b} s, with H = h0, H0, A0, are investigated in the Minimal Supersymmetric Standard Model with non-minimal flavour violation at the one-loop level. The dominating SUSY-QCD contributions with squark--gluino loops are calculated and discussed. The SUSY scenario with non-minimal flavour mixing in the down-type squark-mass matrix is considered, and the flavour-changing effects in terms of the cross sections are derived and discussed, in dependence of the MSSM parameters and the strength of flavour mixing. The values for the cross section can reach 10^{-4} pb for the production of the heavy Higgs boson H0 or A0, and only 10^{-7} pb for the light Higgs boson h0. Non-decoupling behaviour occurs for both h0, H0 production in the case of a common heavy SUSY mass scale.
