On the heavy monopole potential in gluodynamics

We consider predictions for the interaction energy of the fundamental monop oles in gluodynamics introduced via the 't Hooft loop. At short distances, the heavy monopole potential is calculable from first principles. At larger distances, we apply the Abelian dominance models. We discuss measurements which could be crucial to distinguish between various models. Non-zero temp eratures are also considered. (C) 2001 Elsevier Science B.V. All rights res erved.
