Supersymmetric contributions to B$^{0}\overline{B}^{0}$ and K$^{0}\overline{K}^{0}$ mixings

We show that in the supersymmetric standard model (SSM) box diagrams mediated by charginos and up-type squarks may give large contributions to \BB and \KK mixings. This is due to the fact that a heavy top quark mass allows large mass differences among the up-type squarks, which leads to a less effic...
