Revisiting the OZI-forbidden Radiative Decays of Orthoquarkonia

Gang Li, Tong Li, Xue-Qian Li +2

It is interesting to investigate the OZI-forbidden radiative orthoquarkonium decays $J/\psi \to \gamma {\pi }^0,\gamma \eta$ and $\gamma {\eta }^{\prime }$ in perturbative QCD. In this work without the approximations adopted…
