Abstract

In this work we attempt to answer the question whether observed strangeness production could be the result of normal hadronic interactions. We calculated strangeness production in relativistic heavy-ion collisions using the HIJET event generator. HIJET is a Monte Carlo code which considers binary NN collisions and includes secondary interactions and nuclear cascading. HIJET has been very successful in reproducing global experimental results such as E_T distributions, dN dY, etc., in AA as well as pA collisions. We have included various channels which contribute to strangeness production and strangeness exchange in secondary interactions. Our calculations are in good agreement with measurements of strange-particle production (K's and Λ's) in p-Au and O-Au collisions at 200 GeV/A. We cannot account for the increase in the ratio of strangeness to multiplicity as a function of centrality, reported for SS collisions at 200 GeV/A.
