摘要：

We study the role of the scalar resonances f(0)(1370), f(0)(1500), and f(0)(1710) in the strong and radiative three-body decays of J/psi with J/psi -> V + PP(gamma gamma) and J/psi -> gamma PP(VV), where P(V) denotes a pseudoscalar (vector) meson. We assume that the scalars result from a glueball-quarkonium mixing scheme while the dynamics of the transition process is described in the phenomenological Lagrangian approach. The present data on J/psi -> V + PP are well-reproduced; predictions for the radiative processes serve as further tests of this scenario.
