The recent measurements of V→Pγ decays have led to a number of theoretical formulations to explain the low rates. In the vector-meson-dominance model this is accomplished by introducing a suppression factor at one of the vertices of the off-shell vector meson, but this leads to inconsistencies when compared with experimental data. For the case of new mesons we have found that suppression factors need to be introduced at both vertices to give a good fit to the data. In this paper we show that this scheme, applied to the case of the old mesons assuming only simple SU(3), gives fits that are as good as or better than other generally more complicated models. © 1978 The American Physical Society.
