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 $\text{Br}({\chi }_0\to \omega \omega )$ is in a good agreement with the experimental data, while $\text{Br}({\chi }_{c2}\to \omega \omega )$ differs from the experiment significantly.
