论文摘要
描述规格的结构是物理学中最有趣的问题之一。在这方面，广义的Parton分布（GPD）构成了一个出色的工具，可以绘制Hastron内部的“三维图片”。从PION的GPD的当代模型开始满足QCD施加的所有限制，我们计算了经过深度虚拟康普顿散射的乳腺的compton形式（CFF）。我们显示了在EIC的运动学上以Gluon为主导的CFF的行为。最后，我们在沙利文过程中评估了Lepton-beam-Spin不对称性，证明了这种情况的存在，从而引发了人们对在电子胶体上探测Pion 3D结构的可能性的乐观。
Describing hadronic structure is one of the most intriguing problems in physics. In this respect, generalized parton distributions (GPDs) constitute an outstanding tool, allowing to draw "three dimensional pictures" of hadron's inside. Starting from contemporary models for pion's GPDs fulfilling all constraints imposed by QCD, we compute Compton form factors (CFFs) of pions subjected to deeply virtual Compton scattering. We show the behaviour of CFFs to be gluon-dominated at EIC's kinematics. Finally we evaluate lepton-beam-spin asymmetries in the Sullivan process, demonstrating the existence of such and thus triggering optimism about the possibility of probing pion's 3D structure at electron-ion colliders.
