ϕ(2170) production in the process γp→ηϕp

We have studied the γp→ηϕp reaction within the effective Lagrangian approach by considering the contribution of the intermediate state ϕ(2170) production, and the background contributions of t-channel π0 and η mesons exchanges with the intermediate states N and N(1535). Our calculations show that th...

Description
Summary:We have studied the γp→ηϕp reaction within the effective Lagrangian approach by considering the contribution of the intermediate state ϕ(2170) production, and the background contributions of t-channel π0 and η mesons exchanges with the intermediate states N and N(1535). Our calculations 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.
