Quark anomalous moments and meson radiative decays

Abstract

It is shown within the framework of the naive quark model that the measured rates $\Gamma (\rho \to \pi \gamma )$ and $\Gamma (K^{*0\mathrm{}}\to K^0\gamma )$ can be explained if the quarks have anomalous magnetic moments. However, one is led to contradictions with the measured baryon magnetic moments and other measured radiative rates.
