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

The static qq̄ potential is measured on 24³×{}10, 24³×{}12, 12³×{}24, and 16³×{}24 lattices at β=6.0 with high statistics. Using Wilson line operator-operator correlations, we find √σΛL77 and α0.58. 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.
