- W1490490615 abstract "The role of higher meson resonances with spin 1 and 2 is investigated quantitatively in the decay processes of $rho to pi^0pi^0 gamma$ and $omega to pi^0 pi^0 gamma$. Among the higher resonances, we find that the $f_2(1270)$ tensor meson can give a nontrivial contribution especially to the $omega to pi^0 pi^0 gamma$ decay process. When the $f_2$ contribution is combined with the processes involving the vector and scalar meson intermediate states, a good agreement with the recent measurements is achieved for both decays. The effect of the $f_2(1270)$ is found to be sizable at the intermediate photon energies and may be verified by precise measurements of the recoil photon spectrum of the $omega to pi^0 pi^0 gamma$ decay. The dependence of the decay widths on various models for the $rho$-$omega$ mixing in the literature is also investigated." @default.
