本文给出证明：标准模型中CKM矩阵无质量单圈重整化群跑动的6个单圈阶不动点，在微扰论所有阶中均为不动点；此前的证明需对跑动施加额外假设，而本文的证明消除了该额外假设。
英文摘要
A proof is given that the six fixed points of the massless 1-loop renormalization group running of the CKM matrix in the Standard Model found previously at 1-loop are fixed points to all orders in perturbation theory. A previous proof required an extra assumption on the running which is eliminated in the proof presented here.
