AI中文摘要：
深度非弹性散射（DIS）因概念简单，常作为量子色动力学（QCD）及核子部分子结构的教材示例。但正是这种所谓的简单性，使其成为讨论诸多额外效应与修正的理想案例。在这些讲座中，我们在微扰QCD框架下探讨DIS，涵盖从数学问题到运动学修正，再到解读实验测量时的实际挑战等一系列主题。尽管此处聚焦DIS这一示例案例，但所讨论的主题适用于更广泛的过程类别。我们还概述了现有及未来的DIS测量，并探讨其在现代部分子分布函数（PDF）提取中的应用，PDF用于量化核子的部分子结构。所讨论的所有特征均已在开源代码Yadism中实现，该代码已用于从广泛可用的全包含DIS世界数据中提取PDF。
英文摘要：
Due to its conceptual simplicity, Deeply Inelastic Scattering (DIS) often serves as a textbook example for Quantum Chromo Dynamics (QCD) and partonic structure of nucleons. However, it is this supposed simplicity, which makes DIS an ideal case for discussing many additional effects and corrections. In these lectures we discuss DIS within the domain of perturbative QCD covering a range of topics ranging from mathematical problems to kinematical corrections, and to practical challenges when attempting to interpret experimental measurements. Although here we focus on the exemplary case of DIS, the discussed topcis are relevant to a larger class of processes. We also give an overview of existing and future DIS measurements, and discuss their implementation into modern extractions of parton distribution functions (PDFs) which quantify the partonic structure of nucleons. The discussed features are all implemented in the open source code Yadism, which has been used for PDF extractions from a wide range of the available world data on fully inclusive DIS.
