关于Wess-Zumino模型中真空能消失的讨论

Comment about the vanishing of the vacuum energy in the Wess-Zumino model

Andrei O. Barvinsky, Alexander Yu. Kamenshchik, Tereza Vardanyan

摘要:

我们检查Wess-Zumino模型中的真空能量的取消在两个回路的顺序中的分量场形式主义有和没有辅助场。我们证明了在这两种情况下真空能都等于零。然而,在排除辅助场的形式中,真空能的消失是由于势能和动能之间的抵消而产生的,而在有辅助场的形式中,两项分别消失。

英文摘要:

We check the cancellation of the vacuum energy in the Wess-Zumino model at the two-loop order in the component field formalisms with and without auxiliary fields. We show that in both cases the vacuum energy is equal to zero. However, in the formalism where the auxiliary fields are excluded, the vanishing of the vacuum energy arises due to the cancellation between the potential and kinetic energies, while in the formalism with the auxiliary fields, both terms vanish separately.
