标题： A novel probe of the vacuum of the lattice gluodynamics

摘要： 我们引入了一个给定的SU(2)场原始配置在格点上的负链接的最小数量的概念。 负链接对应于大势能，不一定是大作用量。 其思想是，负链接的最小数量是一个规范不变的概念。 为了验证这个假设，我们测量了两个负链接的相关函数，该相关函数是所有方向上的平均值，作为链接之间距离的函数。 反相关长度在误差范围内与最轻的胶球质量一致。 显示英文摘要

摘要： We introduce a notion of minimal number of negative links on the lattice for a given original configuration of SU(2) fields. Negative links correspond to a large potential, not necessarily large action. The idea is that the minimal number of negative links is a gauge invariant notion. To check this hypothesis we measure correlator of two negative links, averaged over all the directions, as function of the distance between the links. The inverse correlation length coincides within the error bars with the lightest glueball mass.
