production at AGS energies

abstract

• A relativistic transport model is used to study - production in 2-11 AGeV Au+Au collisions. Introducing the strangeness-exchange reactions between antikaons and hyperons as the sources for - , we find that the cascade yield in these collisions is in reasonable agreement with the data. Although the - 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. 2004 Elsevier B.V.
