✦ Synopsis

The 't Hooft criterion leading to confinement out of a percolating cluster of central vortices suggests defining a novel three-dimensional gauge theory directly on a random percolation process. Wilson loop is viewed as a counter of topological linking with the random clusters. Beyond the percolation threshold large Wilson loops decay with an area law and show the universal shape effects due to flux tube fluctuations.

Wilson loop correlators define a non-trivial glueball spectrum.

The crumbling of the percolating cluster when one periodic direction na,rrows accounts for the finite temperature deconfinement, which belongs to 2D percolation universality class.
