Study of the rare decay $J/\psi\rightarrow e^+e^- \phi$

We study the decay process of $J / ψ \to e^{+} e^{-} ϕ$ where the relatively clean electromagnetic (EM) transitions appear at leading order at tree level while the hadronic contributions only emerge via hadronic loop transitions. We include the low-lying scalar $f_{0} (980)$ and pseudoscalar $η / η^{'}$ as the dominant contributions in the evaluation of the hadronic loop contributions. It is found that the hadronic effects are negligible comparing with the EM contributions. The decay width of $J/\psi\rightarrow e^+e^- \phi $i s d e t e r m i n e d t o b e a b o u t$ 2.12\times 10^{-6}$ keV if there is no any other leading mechanism contributing, and this result will be tested by the BESIII experiment with a large data sample of $J / ψ$ .
