论文摘要
使用非扰动Pomeron Exchange方法的Electron-Proton（$ EP $）碰撞的专用$ρ^0 $光生效的弹性差异和集成总横截面。通过使用基于Regge现象学的三种不同模型，将结果与H1合作在$ EP $碰撞中的最新测量以及超质质质子铅碰撞的CMS协作进行了比较。通过计算连贯的核横截面（$σ（γa\rightarrowρ^0 a）$）扩展分析，该$适用于超遗传铅铅和Xenon-Xenon碰撞中的$ρ^0 $生产。将预测与爱丽丝协作进行的测量进行了比较。对形式主义的理论不确定性和局限性的各个方面进行了审查。
The elastic differential and integrated total cross section for the exclusive $ρ^0$ photoproduction in electron-proton ($ep$) collisions are evaluated taking into account nonperturbative Pomeron exchange approach. By using three different models based on Regge phenomenology the results are compared to recent measurements by H1 Collaboration in $ep$ collisions and by the CMS collaboration from ultraperipheral proton-lead collisions. The analysis is expanded by calculating the coherent nuclear cross section, $σ(γA\rightarrow ρ^0 A)$, which is applied to $ρ^0$ production in ultraperipheral lead-lead and xenon-xenon collisions. The predictions are compared to the measurements performed by ALICE Collaboration. Aspects of the theoretical uncertainties and limitations of the formalism are scrutinized.
