    "abstract": "Ratios of hadronic abundances are analyzed for pp and nucleus-nucleus\ncollisions at sqrt(s)=20 GeV using the microscopic transport model UrQMD.\nSecondary interactions significantly change the primordial hadronic cocktail of\nthe system. A comparison to data shows a strong dependence on rapidity. Without\nassuming thermal and chemical equilibrium, predicted hadron yields and ratios\nagree with many of the data, the few observed discrepancies are discussed.",
