摘要

本文在假设j(2170)为常规ss¯态的前提下，首次利用双胶子交换模型和有效波美子交换模型研究了γp→j(2170)p的产生。数值结果表明，在W=7 GeV的质心能量下，ϕ(2170)通过γp散射的总截面可以达到70 nb以上。对两种模型的结果进行比较后发现了微妙的差异。此外，在ϕ(2170)光生成截面的基础上，我们利用布鲁克海文国家实验室（BNL）开发的STARlight和eSTARlight程序，系统分析了超外围对撞（UPCs）和电子-离子对撞机（EICs）中ϕ(2170)的产生。因此，根据加速器实验预测了j(2170)通过EIC和UPC的截面、事件数和快速性分布。这些预测为即将在 EicC、EIC-US、RHIC 和大型强子对撞机设施上进行的实验提供了宝贵的理论见解。

Probing strangeonium ϕ(2170) state in lepton-proton scattering and ultra-peripheral collisions

In this work, the production of $γ p \to ϕ (2170) p$ is studied for the first time by using the two gluon exchange model and effective Pomeron exchange model under the assumption that ϕ(2170) is a conventional $s \bar{s}$ state. On the whole, the numerical results show that the total cross section of $ϕ (2170)$ through γp 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 $ϕ (2170)$ photoproduction, we systematically analyzed the production of $ϕ (2170)$ 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 $ϕ (2170)$ 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.
