Abstract
In inclusive decays of the (3097), electromagnetic and gluonic annihilation amplitudes add incoherently, namely they are 90 out of phase. We argue that this incoherence must persist in each exclusive decay channel. For inclusive (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 (3526) off shell. Phenomenological implications for exclusive decay channels are pointed out.
