The SUSY Flavor Problem, Proton Decay and Discrete Family Symmetry
  We consider a supersymmetric extension of the standard model, which possess a family symmetry based on a binary dihedral group Q6, and investigate the consequences of the family symmetry on the mixing of fermions, FCNCs and the stability of proton.
