We introduce the notion of a 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 to large action. The idea is that the minimal number of negative links is a gauge invariant notion. To verify this hypothesis, we measure the correlator of two negative links, averaged over all the directions, as a function of the distance between the links. The inverse correlation length coincides within the error bars with the lightest glueball mass.
