英文摘要	Based on the branching fractions of J/psi -> VP from different experiments, we investigate the properties of the coupling constants of J/psi -> VP decays using a model-dependent approach. We find that the octet coupling constant, g(8), of strong interaction is about twice larger than that of the singlet coupling constant g(1); the electromagnetic breaking parameters g(M)(i) are larger than the mass breaking parameters g(M)(i), moreover, the three parameters of the electromagnetic effect are about equal, but the three parameters of the mass effect are obviously different and their uncertainties are also large; and the phase angle between strong and electromagnetic interactions is in the range of 70 degrees-80 degrees. It deepens our understanding of the coupling constant of J/psi -> VP decays.
