The $\varphi (2170)$ production in the process $\gamma p\to \eta \varphi p$

Guan-Ying Wang, Chen-Guang Zhao, En Wang +2

We have studied the $\gamma p\to \eta \varphi p$ reaction within the effective Lagrangian approach, and our results show that there may be a peak, at least a bump structure around 2180 MeV associat…
