Abstract: (Elsevier)
The success of the Okubo-Iizuka-Zweig rule for decays of Ψ and Ψ′ suggests that the radiative decays Ψ → γ + hadrons should be dominated by intermediates like Ψ → Ψ′ hadrons. This mechanism is consistent with experimental data which show Γ ( Ψ → ϱ 0 π 0 ) and Γ ( Ψ → ηγ ) to be comparable. if all Ψ-like particles are isoscalar, Γ(Ψ → 0 γ) should be very small. If all Ψ-like particles are SU(3) singlets, Γ ( Ψ → η ′ γ )/ Γ ( Ψ → ηγ ) should be large. Substantial violation of our predictions would be circumstantial evidence for the existence of non-singlet new quarks.- J/psi(3100): RADIATIVE DECAY
