Abstract
We extend the simple scenario for ΨⲠdecays suggested a few years ago. The cc¯ pair in the ΨⲠdoes not annihilate directly into three gluons but rather survives before annihilating. An interesting prediction is that a large fraction of all ΨⲠdecays could originate from the Ψâ²âηc(3Ï) channel which we urge experimentalists to identify. Our model solves the problem of the apparent hadronic excess in ΨⲠdecays as well as the ÏÏ puzzle since, in our view, the two-body decays of the ΨⲠare naturally of electromagnetic origin. Further tests of this picture are proposed, e.g., J/Ψâb1η.
