摘要：

In this work, the production of gamma p -> phi(2170)p is studied for the first time by using the two gluon exchange model and effective Pomeron exchange model under the assumption that phi(2170) is a conventional s (s) over bar state. On the whole, the numerical results show that the total cross section of phi(2170) through gamma p scattering can reach more than 70 nb at a center-of-mass energy of W=7 GeV. A comparison between the outcomes of the two models reveals subtle discrepancies. Moreover, base on the cross section of phi(2170) photoproduction, we systematically analyzed the production of phi(2170) at Ultra-Peripheral Collisions (UPCs) and Electron-Ion Colliders (EICs) by using the STARlight and eSTARlight program developed by Brookhaven National Laboratory (BNL). Accordingly, the cross section, event number and rapidity distribution of phi(2170) through EICs and UPCs are predicted based on the accelerator experiments. These projections offer valuable theoretical insights for forthcoming experiments at EicC, EIC-US, RHIC, and LHC facilities.
