The $ϕ(2170)$ production in the process $γp\to ηϕp$

We have studied the $γp\to ηϕp$ reaction within the effective Lagrangian approach, and our results show that there may be a peak, at least a bump structure around 2180 MeV associated to the resonance $ϕ(2170)$ in the $ηϕ$ mass distribution. We suggest to search for the resonance $ϕ(2170)$ in this reaction, which would be helpful to shed light on its nature.
