Note on spin tests for intermediate resonances in doubly radiative three-sequence quarkonium decays
Abstract:In three-sequence doubly radiative quarkonium decays, the double angular correlation function between the two photons has been found to be inadequate for determining the spin of the intermediate resonance. We have shown that a third angular correlation between the second photon and final lepton fixes the spin of the intermediate resonance in all cases, even when the double correlation function of the two photons is unable to do so.
