Abstract
We present calculations of inclusive production of heavy quarkonia via the subprocess\(e^ + e^ - \to MQ\bar Q (M = (Q\bar Q))\). In the particular caseM=J/ψ (Q=c) this subprocess competes significantly with other mechanisms which produce final state gluons. Thus inclusiveJ/ψ production cannot be used to study gluonic jets, as has been suggested. We also present results for the total cross-section of inclusive γ andη c production via the same mechanism.
