Chemical nonequilibrium in high-energy nuclear collisions
Chemical nonequilibrium in high-energy nuclear collisions
Strange particles produced in S-Au/W/Pb 200 A GeV and Pb-Pb 158 A GeV reactions are described invoking final hadronic phase space in thermal equilibrium, but allowing chemical nonequilibrium. Several sets of statistical freeze-out parameters are obtained for each system, invoking different models of dense matter. We show that only when …
