Evidence for Improved Scaling of SU(2) Gauge Theory on a Body-Centered Hypercubic Lattice

The SU(2) string tension is obtained from measurements of Wilson loops on a $6^4$ bodycentered hypercubic lattice. A crude perturbative determination of $\Lambda$ indicates that the results are consistent with those of the hypercubic lattice. However, the $\chi \mathrm{}\left(2\right)\mathrm{}$ loop ratio is found to follow the asymptotic-freedom curve for a much larger range of $g_0$ than has ever been observed for any hypercubic actions. This strongly indicates that the bodycentered lattice may, for a given amount of computer run time, greatly increase the reliability of nonperturbative calculations.
