Abstract: (Elsevier)
We discuss the mixing of pseudoscalar mesons, in particular SU(3) breaking effects, based on ideas abstracted from QCD. The admixtures of η and η′ in η c are calculated and utilized to estimate the M1 radiative decays ψ → ηγ , η′γ. A reasonably consistent picture emerges for these decays as well as others involving only the light quarks.
