Open charm effects in $e^{+}{e}^{-}\to J/\psi \eta$, $J/\psi {\pi }^0$ and $\varphi {\eta }_c$

Qian Wang, Xiao-Hai Liu, Qiang Zhao

We propose to study the open charm effects in $e^{+}{e}^{-}\to J/\psi \eta$, $J/\psi {\pi }^0$ and $\varphi {\eta }_c$. We show that the exclusive cross section lineshapes of these processes would be strongly affec…
