Heavy quark potential in the instanton liquid model
Abstract
We study the heavy quark potential in the instanton liquid model by carefully measuring Wilson loops out to a distance of order 3 fm. A random instanton ensemble with a fixed radius ρ = {1}/{3}fm generates a potential V( R) growing very slowly at large R. In contrast, a more realistic size distribution growing as ρ 6 at small ρ and decaying as ρ -5 at large ρ, leads to a potential which grows linearly with R. The string tension, however, is only about {1}/{10} of the phenomenological value.
