强耦合Toy Model β函数性质分析

Analysis of Strong Coupling Toy Model β Function

本文利用背景场量子化方法对一具有SU(3)对称性的强耦合 Toy Model中规范场Q_μ~1和Q_μ~3的β函数进行了讨论,得出的β函数在低能极限下与Appelquist-Carrazone定理相一致。

In this paper, the background field quantization is used to discuss the βfunction of two gauge field Q_μ~8 and Q_μ~1 in the Toy Model which has the strongcouplingand the SU(3) symmetry. In the low energy condition, the limt of βfunction obeys the Appelquist-Carrazone theorem.
