摘要：
We present flavour-symmetric results for the OZI-allowed couplings of quark–antiquark systems to meson–meson channels in the harmonic-oscillator expansion. We tabulate their values for all possible open and closed decay channels of pseudoscalar, vector, and scalar mesons. We compare the predictions of a model that employs these flavour-symmetric couplings, both with the results of a model which uses explicitly flavour-dependent couplings, and with experiment.
