摘要对于四维空间的杨-米尔斯理论，我们提出了一种只依赖于群因子的普适方法，来重新调整拓扑磁化率与弦张力平方之比。我们将这一建议SU（NC）和SP（NC）组，并比较晶格测量几个独立的合作。我们表明，这两个系列的（重新标度）数值结果在这两个家庭的群体是相互兼容的。因此，我们进行组合拟合，并外推到常见的大N c极限。
Abstract For Yang-Mills theories in four dimensions, we propose to rescale the ratio between topological susceptibility and string tension squared in a universal way, dependent only on group factors. We apply this suggestion to S U (N c) and S p (N c) groups, and compare lattice measurements performed by several independent collaborations. We show that the two sequences of (rescaled) numerical results in these two families of groups are compatible with each other. We hence perform a combined fit, and extrapolate to the common large-N c limit.
