两个相互作用的标量场:实用重整化

Two interacting scalar fields: practical renormalization

S. R. Juárez Wysozka, Piotr Kielanowski, Edgar Uribe Longoria, Liliana Vazquez Mercado

摘要:

本文的主要内容是详细讨论由两个相互作用的标量场组成的量子场论的重整化。模型的势是场的四阶齐次多项式,关于变换$ϕ_{i}\rightarrow{-ϕ_{i}}$对称。我们确定的费曼规则的模型,然后我们提出了一个详细的讨论在一个循环的理论重整化。其次,我们导出了单圈重整化群方程,其中包括运动质量和耦合常数。在两圈层次上,利用Mathematica的FeynArts软件包生成了两圈费曼图,并详细计算了落日图。

英文摘要:

The main theme of the paper is the detailed discussion of the renormalization of the quantum field theory comprising two interacting scalar fields. The potential of the model is the fourth-order homogeneous polynomial of the fields, symmetric with respect to the transformation $ϕ_{i}\rightarrow{-ϕ_{i}}$. We determine the Feynman rules for the model and then we present a detailed discussion of the renormalization of the theory at one loop. Next, we derive the one loop renormalization group equations for the running masses and coupling constants. At the level of two loops, we use the FeynArts package of Mathematica to generate the two loops Feynman diagrams and calculate in detail the setting sun diagram.
