论文摘要
普遍的Parton分布（GPD）是重要的非扰动功能，可提供Hadron的党结构的层析成像图像。我们介绍了一种独家过程，称为单个衍射硬性独家过程（SDHEPS）。我们讨论了将SDHEP分解为GPD的必要条件。我们证明，SDHEP不仅足以涵盖提取GPD的所有已知过程，而且还充分动机搜索了研究GPD的新过程。我们检查了SDHEP对Parton动量分数$ x $依赖性的敏感性。
Generalized parton distributions (GPDs) are important nonperturbative functions that provide tomographic images of partonic structures of hadrons. We introduce a type of exclusive processes, to be referred to as single diffractive hard exclusive processes (SDHEPs). We discuss the necessary and sufficient conditions for SDHEPs to be factorized into GPDs. We demonstrate that the SDHEP is not only sufficiently generic to cover all known processes for extracting GPDs, but is also well motivated for the search of new processes for the study of GPDs. We examine the sensitivity of the SDHEP to the parton momentum fraction $x$ dependence of GPDs.
