  We investigate for the first time the influence of hyperon-nucleon (YN)
interaction models on the strangeness dynamics of antiproton- and $\Xi$-nucleus
interactions. Of particular interest is the formation of bound
multi-strangeness hypermatter in reactions relevant for \panda. The main
features of two well-established microscopic approaches for YN-scattering are
first discussed and their results are then analysed such that they can be
applied in transport-theoretical simulations. The transport calculations for
reactions induced by antiproton beams on a primary target including also the
secondary cascade beams on a secondary target show a strong sensitivity on the
underlying YN-interaction. In particular, we predict the formation of
$\Xi$-hypernuclei with an observable sensitivity on the underlying
$\Xi$N-interaction. We conclude the importance of our studies for the
forthcoming research plans at FAIR.
