Abstract

A relativistic transport model is used to study Ξ^- production in 2-11 AGeV Au+Au collisions. Introducing the strangeness-exchange reactions between antikaons and hyperons as the sources for Ξ^-, we find that the cascade yield in these collisions is in reasonable agreement with the data. Although the Ξ^- abundance does not reach chemical equilibrium unless the cross section for strangeness-exchange reactions is enhanced by six times, it exhibits the strongest enhancement with increasing centrality of collision and with increasing beam energy.
