Radiative decays of heavy and light mesons in a quark triangle approach

Abstract

The radiative meson decays $V\to P\gamma$ and $P\to \gamma \gamma$ are analyzed using the quark triangle diagram. Experimental data yield well determined estimates of the universal quark-antiquark-meson couplings $g_{Vq{\bar{q}}^{\prime }}$ and $g_{Pq{\bar{q}}^{\prime }}$ 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.
