When the scale is set by the string tension, the action density, topological susceptibility and low-lying glueball spectrum are similar to those arising in lattice QCD. The physical mechanism producing confinement is explained, and a number of analytical insights into the effective theory are presented.53 pages, 41 figuresHigh Energy Physics - PhenomenologyHigh Energy Physics - LatticeNuclear Theorytext
