Abstract

We examine the radiative omega-->pi(0)etagamma and rho-->pi(0)etagamma decays in a phenomenological framework. We consider the vector meson dominance mechanism, chiral loops, intermediate a(0)-meson and rho-omega mixing. We find the values of the decay width coming from the different amplitudes and compare the results with other studies. We observe that the a(0)-meson intermediate state is very important in the case of the rho-->pi(0)etagamma decay and small in the other case for which vector meson dominance contribution is dominant.
