Abstract

Using the ARGUS detector at thee + e storage ring DORIS II, we have investigated inclusive production of π±,K ±,K 0 s and\(\bar p\) in multihadron events at 9.98 GeV and in direct decays of the ϒ(1S) meson, i.e. from quark and gluon fragmentation. The most pronounced difference is the rate of baryon production. The Lund Monte Carlo program gives a reasonable qualitative description, although it cannot reproduce our data in detail.
