论文摘要
使用重新归一化的组改进技术，我们研究了由$ n $标量场$ ϕ^i $组成的模型的有效潜力，以$ O（n）$组的基本表示形式转换，并通过六维空间时间定义的立方体交互与附加标量$σ$耦合。我们发现该模型提出了一个可以长寿命的亚稳态真空，颗粒变得巨大。在这种现象中，有吸引力和排斥性相互作用的存在起着至关重要的作用。
Using the renormalization group improvement technique, we study the effective potential of a model consisting of $N$ scalar fields $ϕ^i$ transforming in the fundamental representation of $O(N)$ group coupled to an additional scalar field $σ$ via cubic interactions, defined in a six-dimensional spacetime. We find that the model presents a metastable vacuum, that can be long-lived, where the particles become massive. The existence of attractive and repulsive interactions plays a crucial role in such phenomena.
