The results show that heavy quarks are confined by a linearly rising potential and gluons cannot propagate over large distances. The 't Hooft loop shows a perimeter law and thus also indicates confinement.7 pages, 2 figures, proceedings of the XXV International Symposium on Lattice Field Theory, July 30-4 August 2007, Regensburg, GermanyHigh Energy Physics - TheoryHigh Energy Physics - LatticeHigh Energy Physics - Phenomenologytext
