We present the one-loop effective action up to dimension eight after integrating out degenerate scalars using the Heat-Kernel method. The result is provided without assuming any specific form of either UV or low energy theories, i.e., universal. In this paper, we consider the complete effects of only heavy scalar propagators in the loops. We also verify part of the results using the covariant diagram technique.

高达八维的单循环有效操作:对重标量进行积分

在使用热核方法积分简并标量后,我们提出了高达 8 维的单循环有效作用。提供的结果没有假设任何特定形式的紫外线或低能理论,即通用的。在本文中,我们考虑循环中仅重标量传播器的完整效果。我们还使用协变图技术验证了部分结果。
