标题： On the significance of radiative corrections on measurements of the EMC effect

摘要： 分析关于 EMC 效应的全球数据，该效应表示原子核中的部分子分布函数与自由核子之间的差异，揭示了矛盾。 在杰弗逊实验室进行的精确测量，研究了 x 和 A 的依赖性，显示实验之间存在系统性差异，使得 EMC 效应的 A 依赖性的提取对数据集的选择敏感。 通过比较用于计算辐射修正的各种方法和假设，我们发现了虽然不大但显著影响 EMC 比率的差异，并表明使用一致的辐射修正程序可以解决这一差异，从而形成更连贯的全球图景，并允许更稳健地提取无限核物质中的 EMC 效应。 显示英文摘要

摘要： Analyzing global data on the EMC effect, which denotes differences in parton distribution functions in nuclei compared to unbound nucleons, reveals tensions. Precise measurements at Jefferson Lab, studying both x and A dependence, show systematic discrepancies among experiments, making the extraction of the A dependence of the EMC effect sensitive to the selection of datasets. By comparing various methods and assumptions used to calculate radiative corrections, we have identified differences that, while not large, significantly impact the EMC ratios and show that using a consistent radiative correction procedure resolves this discrepancy, leading to a more coherent global picture, and allowing for a more robust extraction of the EMC effect for infinite nuclear matter.
