Krein空间量化中的标量有效action

Scalar effective action in Krein space quantization

A. Refaei, M V. Takook

摘要:

本文利用Krein空间量子化方法,在单圈近似下计算了λ <$^4标量场有效作用量。我们证明了有效作用量是自然有限的,理论中不存在奇点。计算了物理相互作用质量、运行耦合常数和β函数。在Krein空间量子化中计算的有效势与通常的Hilbert空间量子化中的有效势不同,但我们证明了在两种不同的量子化方法中β函数是相同的。

英文摘要:

In this paper, the λϕ^4 scalar feld effective action, in the one-loop approximation, is calculated by using the Krein space quantization. We show that the effective action is naturally fnite and the singularity does not appear in the theory. The physical interaction mass, the running coupling constant and β-function are then calculated. The effective potential which is calculated in the Krein space quantization is different from the usual Hilbert space calculation, however we show that β-function is the same in the two different methods.
