Abstract
We present results on the static potential from high-statistics simulations on , ×32, and lattices, using the standard Wilson action at on the Connection Machine CM2. To decrease noise and increase accuracy, we applied a suitable local smoothing technique on the spatial parts of Wilson loop operators. As a result, we find a violation of asymptotic scaling of the string tension, as signaled by , for the three values, with statistical and systematic errors. We observe a linear confining potential up to distances of 2 fm. A volume of appears to be sufficient to avoid finite-size effects within our statistical accuracy (≅ 1%).
