We have studied stop, sbottom and gluino decays in a scenario with lar
ge tan beta, where both t(L)-t(R) and b(L)-b(R) mixing as well as the
Yukawa couplings have to be taken into account. In particular we have
worked out the case that b1 is the lightest squark. The decay patterns
of sbottom and stop are very different from those of the squarks of t
he first and second generation.
