摘要

A parametrisation of negative hadron and neutral strange particle production was developed which consistently describes presently available data from nucleon-nuceon, nucleon-nucleus, and nucleus-nucleus collisions at a beam energy of 200 GeV per nucleon. Average multiplicities of negative hadrons are found to be proportional to the number of wounded nucleons, average K(sub s)(sup 0) multiplicities proportional to the number of wounded quarks, and average (Lambda) and anti (Lambda) multiplicities proportional to the number of wounded quarks plus an additional contribution proportional to the number of interactions of secondary produced particles. Predictions are given for lead-lead collisions. (orig.) (ERA citation 20:011389)
