Different contributions in ω → π0ηγ and ρ → π0ηγ decays
Özet
We examine the radiative ? › ?0?? and ? › ?0?? decays in a phenomenological framework We consider the vector meson dominance mechanism, chiral loops, intermediate a0-meson and ? - ? 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 a0-meson intermediate state is very important in the case of the ? › ?0?? decay and small in the other case for which vector meson dominance contribution is dominant.
