Abstract

We compute the heavy quark potential on configurations generated by the HEMCGC collaboration with dynamical staggered fermions at 6/g² = 5.6 and with dynamical Wilson fermions at 6/g² = 5.3. The computations are done on 16³ × 32 lattices, corresponding to physical sizes of about 1.6 and 2.3 fm, respectively. Up to the distances probed no sign of string breaking is detectable. We also compute the recently proposed scale r₀ defined by r₀² F(r₀) = 1.65.
