As a phenomenological description of the non-perturbative property of QCD, meson loop mechanism plays a crucial role in understanding some particular decay behaviors of heavy quarkonia. In this talk, I will present our estimations of meson loop contributions to some strong decay process, such as $Upsilon(5S) o omega chi_{bJ}$, $psi(4160)/psi(4040) o eta J/psi$ and $chi_{c1} o VV$. In addition, the meson loop contributions to the radiative transition processes are also discussed. |
