Energy dependence of inclusive and semi-inclusive processes in the quark-cascade jet model. II. Quark-diquark systems

We consider here quark-diquark hadronization for different processes in an integrated manner in a quark-cascade jet-production model proposed recently. With a simple primordial diquark fragmentation function, related to the baryon signal, the model is found to yield reasonable results for average charged multiplicities along with some observed semi-inclusive and exclusive cross sections. Further, we also find a clear indication that at higher energies as well as for larger multiplicities, the quark-cascade jet-production model becomes inadequate and is to be supplemented by other dynamical mechanisms which increase the multiplicity.
