摘要:

本文把我们以前对含无穷导数的阿贝尔U(1)规范理论的讨论推广到非阿贝尔SU(N)的情形。本文计算了SU(N)规范耦合的重整化群方程(RGE),在非定域尺度M $\rightarrow \infty$的极限下再现了定域理论$β$函数。有趣的是,规范耦合停止其运行超过尺度$M$,接近渐近共形理论。

英文摘要:

This paper focuses on extending our previous discussion of an Abelian U(1) gauge theory involving infinite derivatives to a non-Abelian SU(N) case. The renormalization group equation (RGEs) of the SU(N) gauge coupling is calculated and shown to reproduce the local theory $β$-function in the limit of the non-local scale M $\rightarrow \infty$. Interestingly, the gauge coupling stops its running beyond the scale $M$, approaching an asymptotically conformal theory.
