| dc.description | 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 $U(N_f)$ symmetry. We focus primarily on radiative meson decays which involve one pseudoscalar. The agreement with experiment for non-rare decays is surprisingly good and requires very few parameters, namely the coupling constants $g_{πqq}$ and $g_{ρqq}$ and some mixing angles. This agreement extends to some three-body decays that are dominated by pion pairs in a P-wave state. | |
