Supersymmetric Decays of the Top Quark: an update
  We analyze the two decays $\thb$, $\tstn$ within the Minimal Supersymmetric Standard Model with radiative breaking of the electroweak sector. We discuss their detectability at present and in the eventuality that supersymmetry is not discovered at LEPII.
