六维有效势的重整化群改进

Renormalization group improvement of the effective potential in six dimensions

Huan Souza, L. Ibiapina Bevilaqua, A. C. Lehum

摘要:

利用重整化群改进技术,研究了六维时空中由$O(N)$群的基本表示变换的$N$标量场$ϕ^i$通过立方相互作用耦合到一个附加标量场$σ$组成的模型的有效势.我们发现,该模型提出了一个亚稳态真空,可以是长期的,在那里的粒子变得大量。吸引和排斥相互作用的存在在这种现象中起着至关重要的作用。

英文摘要:

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.
