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

TL;DR

This paper investigates the production of the $ ext{phi}(2170)$ resonance in the $ ext{gamma} p o ext{eta} ext{phi} p$ reaction, suggesting a potential peak around 2180 MeV that could help understand its nature.

Contribution

The study provides the first theoretical prediction of a peak associated with $ ext{phi}(2170)$ in this specific reaction using an effective Lagrangian approach.

Findings

Potential peak at 2180 MeV in $ exteta ext{phi}$ mass distribution.

Supports experimental search for $ ext{phi}(2170)$ in this reaction.

Provides insights into the resonance's nature.

Abstract

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