Mass dependence of the particle multiplicity in Υ three gluon fragmentation

The authors found that the final state hadron multiplicities in Υ→3g fragmentation satisfy the same general mass dependence as in e+e-→q0anti q0 events. This indicates that the fragmentation of quarks and gluons to hadrons follows the same mechanism. The important character of increment of the baryon multiplicity in Υ→3g fragmentation is interpreted naturally without any other assumptions
