AI 中文摘要
本章概述了从格点量子色动力学（lattice QCD）提取广义部分子分布（GPDs）的近期进展，简要回顾了GPDs的理论原理，解释了两种最常见的格点方法：Ji的准分布（Ji's quasi-distributions）和Radyushkin的伪分布（Radyushkin's pseudo-distributions）；第二部分综述了这两种框架下获得的格点结果，最后讨论了格点提取GPDs的未来前景。
英文摘要
This chapter gives an overview of the recent progress in extracting generalized parton distributions from lattice QCD. We briefly recall the theoretical principles of GPDs and explain the two most common lattice approaches, Ji's quasi-distributions and Radyushkin's pseudo-distributions. In the second part of the chapter, we review the lattice results obtained from these two frameworks. Finally, we offer a discussion of future prospects of lattice extractions of GPDs.
