Abstract：
From calculation and analysis of the mean light flavor quark production probability in light quark jet events, e^＋e^－→q₀q₀→h′s, which involves electromagnetic interaction and hadronic interaction, we determine the dependence of the mean production rates of particles in light (uds) quark jets on the primary quark flavor and number of quark pairs N. Moreover, the relative production rates of leading hadrons are obtained, which shows a strong correlation with the quark pair number N. These results provide a basis for furture studies of particle production in light favor jet at low center-of-mass energy range.
