论文摘要
我回顾了一些与横向动量依赖性(TMD)Parton相关功能的横向力矩(TMD)相关功能的大横向动量差异有关的开放问题。我还以缩写和汇总的形式解释了最近的工作表明,违反常用的整体关系的行为不会被扰动。我认为这意味着需要更精确的定义来描述横向矩的相关功能。
I review some open questions relating to the large transverse momentum divergences in transverse moments of transverse momentum dependent (TMD) parton correlation func- tions. I also explain, in an abbreviated and summarized form, recent work that shows that the resulting violations of a commonly used integral relation are not perturbatively suppressed. I argue that this implies a need for more precise definitions for the correlation functions used to describe transverse moments.
