格点理论的重整化群分析和改进的格点Action。II --四维非阿贝尔SU（N）规范模型

Renormalization Group Analysis of Lattice Theories and Improved Lattice Action. II -- four-dimensional non-abelian SU(N) gauge model

Y. Iwasaki

备注：
This article, which was not published, was written in December 1983. It proposed an improved gauge action, which has be used in numerical simulations of lattice gauge theories. It is posted for the convenience of referencing. It is the same as was in 1983, a few typographical errors being corrected. 20 pages, 5 figures

摘要：

在微扰论中，提出了SU（N）规范模型在非平凡不动点附近的块自旋重整化群变换，从而明确地得到了不动点附近重整化轨道上各种威尔逊圈的期望值.得到了改进的作用量，并给出了物理量标度行为的判据。

英文摘要：

A new block spin renormalization group transformation for SU(N) gauge models is proposed near the non-trivial fixed point in perturbation theory and thereby the expectation values of various Wilson loops on the renormalized trajectory near the fixed point are explicitly obtained. An improved action is obtained as in a preceding paper and a criterion for the scaling behavior of physical quantities is also given.
