Flavour-changing effects on e+e-→Hb(s)over-bar, H(b)over-bar in the MSSM

Flavour-changing effects originating from the exchange of scalar particles in the processes e(+)e(-) -> H(x)b (s) over bar, H-x(b) over bars, with H-x -> h(0), H-0, A(0), 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. We consider the SUSY scenario with non-minimal flavour mixing in the down-type squark-mass matrix. The flavour-changing cross sections are derived, and we discuss the dependence on the MSSM parameters and the strength of flavour mixing. The values for the cross section can reach 10(-4) ph for the production of the heavy Higgs boson H-0 or A(0), and only 10(-7) pb for the light Higgs boson h(0). Non-decoupling behaviour occurs for both h(0), H-0 production in the case of a common heavy SUSY mass scale.
