Leading twist contribution to color singlet ${\chi }_{c0,2}\to \omega \omega$ decays

Abstract

In this paper the leading twist contribution to ${\chi }_{c0,2}\to \omega \omega$ decays in the color singlet approximation is considered. It is shown, that the predictions for $\Br(χ_0\toωω)$ is in a good agreement with the experimental data, while $\Br(χ_{c2}\toωω)$ differs from the experiment significantly.
