Higgs-mediated FCNC in Supersymmetic Models with Large $\tanβ$
arXiv:hep-ph/9807350 · doi:10.1103/PhysRevD.59.095005
Abstract
In the supersymmetric models with nontrivial flavour structure in the soft-breaking sector the exchange of neutral Higgses mediates $ÎF=2$ transitions. This mechanism is studied for $ÎS, ÎB=2$ processes and for a generic form of the soft-breaking terms. We find that Higgs-mediated FCNC amplitudes increase very rapidly with $\tanβ$ and can exceed $SUSY$ box contribution by up to two orders of magnitude when $\tanβ\sim m_t/m_b$.
