Abstract
A MC generator incorporating the new features of hadronic multiproduction, observed at the CERN collider with the European hybrid spectrometer, has been developed using considerations based on the dual parton model. This semi-empirical model is especially efficient at reproducing the complex characteristics of semi-inclusive data under the principle of scaling in the central region for relative rapidity density against z, and violation of KNO scaling. Extended to include p-A collisions, such as a triple-Gaussian random generator, it has been inserted in a cosmic-ray cascade simulation.
