Strange Particle Production from SIS up to 40 A·GeV

  • Helmut Oeschler
Article

Summary

<p>A review of strange particle production in heavy ion collisions at incident energies from SIS up to 40 <i>A</i>·GeV is presented. A statistical model assuming chemical equilibrium and local strangeness conservation (i.e. strangeness conservation per collision) describes most of the observed features.</p>  <p>It is demonstrated that the K- production at SIS energies occurs predominantly via strangeness exchange and that this channel is approaching chemical equilibrium. The observed maximum in the K+/&pi;+ excitation function is also seen in the ratio of strange to non-strange particle production. The appearance of this maximum around 30 <i>A</i>·GeV is due to the energy dependence of the chemical freeze-out parameters temperature <i>T</i> and baryo-chemical potential &mu;B.
