| Abstract | Under the assumption of hard scattering, multiplicity analysis of quark-diquark jets is made in a model analogous to the quark-cascade- jet production model developed earlier. In the present approach the diquark is treated as a coherent object consisting of the two quarks which remain after the hard scattering. This is assumed to produce a baryon and an antiquark in the first stage of its fragmentation. The resulting quark-antiquark pair then hadronises as per the cascade model. This picture of quark-diquark fragmentation is adequately supported by the observations made in recent ISR experiments at CERN. The above technique is applied to weak, electromagnetic and strong processes involving quark-diquark hadronisation in a unified manner and with fair agreement with the experimental results.
