论文摘要
我们简化了单循环功能匹配的形式主义，以开发精简的处方。功能方法在概念上具有吸引力：所有计算均以匹配量表进行在UV理论中，并且不需要先前确定有效的现场理论（EFT）操作员基础。我们的处方适合任何相对论的紫外线理论，其中包含标量，费米昂和向量场之间的通用相互作用（包括衍生耦合）。作为示例应用程序，我们将Singlet标量扩展标准模型（SM）匹配到SMEFT。
We simplify the one-loop functional matching formalism to develop a streamlined prescription. The functional approach is conceptually appealing: all calculations are performed within the UV theory at the matching scale, and no prior determination of an Effective Field Theory (EFT) operator basis is required. Our prescription accommodates any relativistic UV theory that contains generic interactions (including derivative couplings) among scalar, fermion, and vector fields. As an example application, we match the singlet scalar extended Standard Model (SM) onto SMEFT.
