Double Suppression of FCNCs in a Supersymmetric Model
  A concrete model which can suppress FCNCs and CP violating phenomena is suggested. It is an $S_3$ symmetric extension of the MSSM in extra dimensions, where only SU(2) and SU(3) gauge multiplets are assumed to propagate in the bulk. They are suppressed due to $S_3$ flavor symmetry at $M_{SUSY}$, and the infrared attractive force of gauge interactions in extra dimensions are used to suppress them at the compactification scale. We find that O(1) disorders of the soft parameters are allowed at the cut-off scale to suppress sufficiently FCNCs and CP violating phenomena.
