Abstract / Bemerkung
We analyze the influence of experimentally not yet observed strange hadrons – predicted by quark model calculations as well as lattice QCD – on QCD bulk thermodynamics. By comparing lattice QCD results of various combinations of net strangeness fluctuations to hadron resonance gas (HRG) model calculations with different strange hadron content, we find evidence for such additional hadronic states from QCD thermodynamics. We further investigate the impact of such states on the freeze-out parameter in heavy ion collisions. We show that the freeze-out temperature as determined from yields of strange baryons over anti-baryons is, in agreement with lattice QCD, lowered by 5–8 MeV in comparison with the conventional HRG model calculations.
