论文摘要
我们得出了一种构建有效领域理论的新方法。从物理上讲,该方法非常接近有效场理论背后的直觉:可以直接从路径积分中整合较重的尺度。我们为有效的现场理论构建提供了详细的配方,该配方与所谓的1PI有效作用的构建几乎相同。我们还证明了这种新方法与匹配Green功能的常用过程的等效性。
We derive a novel method for constructing effective field theories. Physically, the method is very close to the intuition behind effective field theories: One can integrate out the heavier scale directly from the path integral. We give a detailed recipe for the effective field theory construction, which is nearly identical to the construction of the so-called 1PI effective action. We also demonstrate the equivalence of the novel method to the commonly used procedure of matching Green's functions.
