Abstract

We study the heavy quark potential in the instanton liquid model by carefully measuring Wilson loops out to a distance of order 3fm. A random instanton ensemble with a fixed radius ρ = 13fm generates a potential V(R) growing very slowly at large R. In contrast, a more realistic size distribution growing as ρ⁶ 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 110 of the phenomenological value.
