Description

Inclusive production of πsup(+-), Ksup(+-) and anti 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 UPSILON and UPSILON' are compared to the off-resonance (continuum) yields with the aim of uncovering differences between three-gluon hadronization and quark-antiquark fragmentation. A noticeable difference is seen in the yield of protons and antiprotons which is (8.1 +- 2.1)% of all charged hadrons for Y decay and (18.9 +- 6.9)% for UPSILON' decay compared to (1.5 +- 1.1)% for non-resonant production.
