摘要：

The radiative decay processes of the type V0P0P0 are described by the gauged Wess-Zumino terms in a low-energy effective Lagrangian, there being no bremsstrahlung contributions. Using such an effective Lagrangian, describing pseudoscalar and vector mesons, we have calculated the branching ratios for the decays 00, 0, 00, 0, 00, 0, and K0K»0. Since scalar mesons have been neglected, these rates provide estimates of the expected backgrounds in searches for J=0+ resonances, particularly the possible four-quark states in decays. © 1990 The American Physical Society.
