论文摘要
在本文中，我们回顾了有关Parton分布的$ x $依赖性的最新晶格计算，后者提供了有关强子结构的信息。这些计算基于与非本地运算符相连的增强的Hadron的矩阵元素，并且可以通过适当的分解形式主义与标准的，轻度的分布函数有关。在几个方向上取得了重大进展，包括风味单线分配函数（PDF），广义Parton分布（GPD）的首次计算，以及实施某些横向依赖性依赖性PDFS（TMD PDF）的方法。对于实验数据集的现象学拟合，晶格计算的新方向特别有趣，因为晶格结果可以帮助改善分布功能的约束。
In this article, we review recent lattice calculations on the $x$-dependence of parton distributions, with the latter providing information on hadron structure. These calculations are based on matrix elements of boosted hadrons coupled to non-local operators and can be related to the standard, light-cone distribution functions via an appropriate factorization formalism. There is significant progress in several directions, including calculations of flavor singlet parton distribution functions (PDFs), first calculations of generalized parton distributions (GPDs), as well as the implementation of some of the approaches for the transverse-momentum-dependent PDFs (TMD PDFs). This new direction of lattice calculations is particularly interesting for phenomenological fits on experimental data sets, as the lattice results can help to improve the constraints on the distribution functions.
