Description
We examine two-body radiative decays of quarkonium states O→γ+zeta in order to study the effects of the spin of the zeta on decay widths; zeta stands for any elementary particle or resonance. Using effective zeta couplings in a calculation which goes beyond the Wilczek approximation, we find that in all cases examined, J/sub zeta/ = 0/sup +- /, 1+, 2/sup +- /, spin has little effect on the ratio Γ(O(2S)→γ+zeta)/ Γ(O(1S)→γ+zeta) except for zeta masses close to the phase-space limit
