A quark model for hadron production

Hadron production in nucleon-nucleon, nucleon-nucleus and nucleus-nucleus interactions is considered in the framework of the Rossendorf collision model, which aims at describing simultaneously all reaction channels in a wide energy region. An empirical matrix element based on the partonic picture of hadrons is combined with the concept of intermediate subsystems and the calculation of modified statistical weights of the various final states. In case of nuclear reactions the Glauber concept is used to calculate the partial cross sections for the interaction of various numbers of participants. It is demonstrated that a large variety of experimental data can be satisfactorily reproduced. Predictions for proposed missing-mass measurements are discussed.
