Leading twist contribution to color singlet $χ_{c0,2}\toωω$ decays

Abstract

In this paper the leading twist contribution to $χ_{c0,2}\toωω$ 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.
