abstract = {We study the production of (hyper-)nuclei and di-baryons in
most central heavy Ion collisions at energies of
$E_{lab}=1-160 A$ GeV. In particular we are interested in
clusters produced from the hot and dense fireball. The
formation rate of strange and non-strange clusters is
estimated by assuming thermal production from the
intermediate phase of the UrQMD-hydro hybrid model and
alternatively by the coalescence mechanism from a hadronic
cascade model. Both model types are compared in detail. For
most energies we find that both approaches agree in their
predictions for the yields of the clusters. Only for very
low beam energies, and for di-baryons including $Xi$'s, we
observe considerable differences. We also study the
production of anti-matter clusters up to top RHIC energies
and show that the observation of anti-$^4He$ and even
anti-$^4_{Lambda}He$ is feasible. We have found a
considerable qualitative difference in the energy dependence
of the strangeness population factor $R_H$ when comparing
the thermal production with the coalescence results.},
