摘要：

The rapidity distribution of Lambda and <(Lambda)over bar> produced in nucleus-nucleus collisions at CERN energies is studied in the framework of an independent string model - with quark-antiquark as well as diquark-antidiquark pairs in the nucleon sea. It is shown that, besides the Lambda-<(Lambda)over bar> pair production resulting from the fragmentation of sea diquarks, final state interactions of co-moving secondaries pi + N --> K + Lambda and pi + (N) over bar --> K + <(Lambda)over bar> are needed in order to reproduce the data, Predictions for Pb-Pb collisions are presented.
