DOIAbstract
Inclusive production of π ± , K ± and p has been measured in e + e − annihilation for center of mass energies between 9.4 and 10.1 GeV. The hadron yields on the resonances ϒ and ϒ' are compared to the off-resonance (continuum) yields with the aim of uncovering differences between three-gluon hadronization and quark-antiquark fragmentation. A noticeable differences is seen in the yield of protons and antiprotons which is (8.1 ± 2.1)% of all charged hadrons for ϒ decay and (18.9 ± 6.9)% of ϒ' decay compared to (1.5 ±1.1.)% for non-resonant production
