Yun-Hua Chen, Zhi-Hui Guo, Bing-Song Zou

Within the framework of the effective Lagrangian approach, we perform a thorough analysis of the $J/\psi \to P\gamma ({\gamma }^{\ast })$, $J/\psi \to VP$, $V\to P\gamma ({\gamma }^{\ast })$, $P\to V\gamma ({\gamma }^{\ast })$ and $P\to \gamma \gamma ({\gamma }^{\ast })$ pro…
