Calculation of the heavy-quark potential at large separation on a hypercube parallel computer

The static $q\overline{q}$ potential is measured on ${24}^3$×10, ${24}^3$×12, ${12}^3$×24, and ${16}^3$×24 lattices at $\beta =6.0\mathrm{}$ with high statistics. Using Wilson line operator-operator correlations, we find $\frac{\sqrt{\sigma }}{{\Lambda }_L\simeq 77}$ and $\alpha \simeq 0.58$. This new result compares favorably with that obtained from charmonium experimental data, but is significantly different from many previous lattice calculations. Our calculations use a hypercube parallel computer which in its full configuration performs at 0.6 gigaflops on this application.
