N=2线性西格玛模型的路径积分方法

The Path-Integral Approach to the N=2 Linear Sigma Model

E. N. Argyres, M. T. M. van Kessel, R. H. P. Kleiss

摘要:

在QFT中,有效势是研究对称性破缺现象的重要工具。众所周知,在某些理论中,正则方法和路径积分方法产生不同的有效势。在本文中,我们研究了欧几里得N=2线性西格玛模型。格林函数和有效势都将用三种不同的方法计算。各种方法的相对优点进行了讨论。

英文摘要:

In QFT the effective potential is an important tool to study symmetry breaking phenomena. It is known that, in some theories, the canonical approach and the path-integral approach yield different effective potentials. In this paper we investigate this for the Euclidean N=2 linear sigma model. Both the Green's functions and the effective potential will be computed in three different ways. The relative merits of the various approaches are discussed.
