摘要：

In inclusive decays of the Psi (3097), electromagnetic and gluonic annihilation amplitudes add incoherently, namely they are 90 degrees out of phase. We argue that this incoherence must persist in each exclusive decay channel. For inclusive Psi' (3686) decays, we suggest the absence of a significant direct annihilation amplitude into three gluons and propose a new amplitude via QCD anomalies and the h(c) (3526) off shell. Phenomenological implications for exclusive decay channels are pointed out. (C) 1999 Elsevier Science B.V. All rights reserved.
