Abstract

We study as function of energy strangeness created in relativistic heavy ion collisions. We consider statistical hadronization with chemical freeze-out in both equilibrium and nonequilibrium. We obtain strangeness per baryon and per entropy in the energy range 8.75sNN 200 A GeV. A baryon density independent evaluation of the kaon to pion ratio is presented.
