Query: (Anti-)strangeness production in heavy-ion collisions   The production and dynamics of strange and antistrange hadrons in heavy-ion
reactions from $\sqrt{s_{NN}} \approx$ 3 GeV to 200 GeV is analyzed within the
Parton-Hadron-String-Dynamics (PHSD) transport model. The PHSD results for
strange baryon and antibaryon production are roughly consistent with the
experimental data starting from upper SPS energies. Nevertheless, hadronic
final state flavor-exchange reactions are important for the actual abundances,
in particular at large rapidities where hadronic dynamics, parton fragmentation
and string decay dominate. A striking disagreement between the PHSD results and
the available data persists, however, for bombarding energies below
$\sqrt{s_{NN}} \approx$ 8 GeV where the strangeness production is significantly
underestimated as in earlier HSD studies. This finding implies that the
strangeness enhancement seen experimentally at FAIR/NICA energies cannot be
attributed to a deconfinement phase transition or crossover but probably
involves the approximate restoration of chiral symmetry in the hadronic phase.
