Abstract: (APS)
The SU(3) deconfinement temperature is studied on asymmetric lattices as a probe of scaling. For lattices with four sites in the temperature direction (βc≈5.7) we find precise agreement between the measured asymmetry dependence of the Λ parameter and that predicted by one-loop perturbation theory. The agreement holds over a large range of asymmetry (0.65<~ξ<~1.1) and implies that violations of perturbative scaling above β≈5.7 are independent of asymmetry and therefore unlikely to be lattice artifacts. This provides evidence that the coupling range 5.7≲β≲6.2 is a regime of nonperturbative but universal scaling.- GAUGE FIELD THEORY: SU(3)
