Quark Loops

We show that all abnormal parity three-body meson interactions can be adequately described by quark loops, evaluated at zero external momentum, with couplings determined by U(Nf) symmetry. We focus primarily on radiative meson decays which involve one pseudoscalar. The agreement with experiment for nonrare decays is surprisingly good and requires very few parameters, namely the coupling constants gπqq and gρqq and some mixing angles. This agreement extends to some three-body decays that are dominated by pion pairs in a P-wave state.

The experimental data on the radiative decays of mesons (not involving charm) are reviewed. The consistency of these data with SU(3) symmetry, vector dominance, and the quark model is discussed.

Radiative Meson Decays

The radiative meson decays V→ Pγ and P →γγ are analysed using the quark triangle diagram. Experimental data yield well determined estimates of the universal quark–antiquark–meson couplings gvqq′ and gpqq′ for the light meson sector. Also predictions for the ratios of neutral to charged heavy meson decay coupling constants are given and await experimental confirmation.
