Predicting the inter-monopole potential in gluodynamics.

Abstract

We discuss predictions for the interaction energy of the fundamental monopoles in gluodynamics. The interaction energy is defined, as usual, in terms of the 't Hooft loop. At short distances, the potential is calculable starting from first principles. At larger distances, we apply the Abelian dominance models. Non-zero temperatures are also discussed. The predictions turn to be in reasonable agreement with the existing data, in cases when the comparison is possible.
