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 $\Br(\chi_0\to\omega\omega)$ is in a good agreement with the experimental data, while $\Br(\chi_{c2}\to\omega\omega)$ differs from the experiment significantly.
