Fragmentation character of resonance events in BEPC e+ e- annihilation

In this paper an important character was found that the final hadron multiplicities of direct J/phi decays satisfy the same universal mass dependence as that in e(+) e(-) --> q(0)(q(0)) over bar continuum events. This indicates that the fragmentation of quark and gluon to hadron follows the same mechanism. We give a reasonable interpretation to final baryon multiplicity that is enhanced by 2.5 times in direct Y decays compared to the continuum through our calculating results. But we cannot find this similar phenomenon in direct J/phi decays.
