Abstract

In the supersymmetric models with a nontrivial flavor structure in the soft-breaking sector the exchange of neutral Higgs bosons mediates ΔF=2 transitions. This mechanism is studied for ΔS,ΔB=2 processes and for a generic form of the soft-breaking terms. We find that Higgs-boson-mediated FCNC amplitudes increase very rapidly with tan β and can exceed SUSY box contribution by up to two orders of magnitude when tan β ∼m_t/m_b.
