A Simple Model for the Quark Fragmentation Functions Seen in Deep Inelastic Processes*

Using some simple .ass.mptions, we present in this paper a calculation of the quark fragmentation functions seen in deep inelastic processes. The results provide evidence for the conjecture that both jets seen in high p1 reactions at the ISR stem from similar parents. The calculated functions are in excellent agreement with the inclusive distributions seen in vp and tp scattering,and in particular explain the puzzling presence of leading IT-'s from the fragmentation of a leading up quark. The results are also in agreement with the charge ratios extracted from deep inelastic electron scattering. * Work supported in part by the Energy Research and Development Administration (Submitted to Phys.
