本文研究了几种五夸克态的电产生。eSTARlight软件包适用于研究电子-离子对撞机（EIC）中的五夸克和共振通道的电产生和散射过程。在这项研究中获得的结果进行比较，非共振t-通道，这是在我们的研究中开发的pomeron交换模型中描述的。给出了EIC-US和EicC的赝快度和快度分布。结果表明，EicC是一个很好的状态识别平台。
Electro-production of several pentaquark states is investigated in this study. The eSTARlight package is adapted to study the electro-production of and via pentaquark and resonance channels in and scattering processes at the proposed electron-ion colliders (EICs). The results obtained in this study are compared to those of non-resonance t-channels, which are described in the pomeron exchange model developed in our studies. Some pseudo-rapidity and rapidity distributions of and are presented for the proposed EICs, including EicC and EIC-US. It is found that EicC is a good platform to identify states in the future.
