Abstract

The branching ratios R(J→ππρ)≡Γ(J→ππρ)/Γ(J→ππ) for natural JP mesons have been evaluated under the assumption that the T(J→ππρ) amplitudes are generated by the gauge principle for ρ-mesons originally proposed by Sakurai in his approach to VMD. The ratios are predicted to increase with J and are compatible with the present-day data. This suggests that the hadronic interactions of the photon proceed exclusively through its hadronic (VMD) component. © 1980 Springer-Verlag.
