论文摘要
将紫外线理论映射到低能量有效描述上是一种称为匹配的过程。在过去的十年中，通过依靠所谓的功能方法，在开发新工具的开发中取得了巨大进展。该白皮书总结了功能匹配的状态。具体而言，相对论理论的匹配是一个完全解决的问题，直至扰动理论中的一环秩序，并在有效的现场理论扩展中进行任意顺序。已部分自动化的简化处方促进了功能匹配在标准模型EFT框架中的现象学研究的应用。
Mapping UV theories onto low energy effective descriptions is a procedure known as matching. The last decade has seen tremendous progress in the development of new tools for efficiently performing matching calculations, by relying on so-called functional methods. This white paper summarizes the status of functional matching. Specifically, matching for relativistic theories is a fully solved problem up to one-loop order in perturbation theory, and to arbitrary order in the effective field theory expansion. A streamlined prescription that has been partially automated facilitates the application of functional matching to phenomenological studies in the Standard Model EFT framework.
