Abstract:

Both linear and quadratic mass-formulas are applied to vector-mesons and pseudoscalar-mesons. We find that the linear mass-formula must be applied to vector-mesons in order to explain the small hadronic decay width of J/φ through the small mixture of ordinary quark-antiquark pairs in J/ψ.
If the linear mass-formula is also applied to pseudoscalar-mesons, we find (i) M(F) > M(F^*) and (ii) M(η_c) ≧2.80 GeV.
The hadronic decay widths of η_c and γ-decay widths of J/ψ are also discussed.
