Implication of the observed $\psi (3770)\to p\bar{p}{\pi }^0$ for studying the $p\bar{p}\to \psi (3770){\pi }^0$ process

Hao Xu, Ju-Jun Xie, Xiang Liu

We study the charmonium $p\bar{p}\to \psi (3770){\pi }^0$ reaction using the effective lagrangian approach where the contributions from well established $N^{\ast }$ states are considered, and…
