Abstract

We make some comments concerning charm-related models, the Schwinger phenomenological theory, and a possible multiplicative t quantum-number scheme for the J and other ψ particles. It is seen that an accurate measurement of the rate J0→π++π−+γ, a search for narrow-width (IG,JP)=(1±,1∓) particles (with the vector particle probably below 3.1 GeV), and a possible enhanced pair production of (JJ) and (Jψ) in hadron-initiated reactions at high energies remain of substantial interest in sorting out our options.
