内容記述 | The compositeness of mesons is taken into account in the evaluation of decays and mixing of η, η′, and ηc with an idea abstracted from quantum chromodynamics. Effective couplings of a pseudoscalar meson and two gluons are calculated in a simple model, where the Bethe-Salpeter amplitude is approximated in terms of harmonic-oscillator wave functions. The model is constructed so as to reproduce S-wave meson masses and the values of wave functions at the origin in the sense of the nonrelativistic quark model. In this model Γ(π0→2γ) is reproduced satisfactorily. We obtain an s-dependent mixing angle, which is estimated to be -42.3° and -40.0° for s=Mη2 and s=Mη′2, respectively. Criticism of various estimations of the angle is presented. All the results are shown to be consistent with experiments. The importance of the compositeness of mesons is stressed. | |||||
