Abstract: (Elsevier)
We study the approach to the continuum limit of SU(2) lattice gauge theory by accurately calculating several physical quantities on lattices up to 20 4 and for couplings up to β =4/ g 2 =2.6. We find that the dependence of mass ratios on the lattice spacing weakens as the spacing decreases, although the two-loop relation between the spacing and g 2 is not yet attained for β ⩽2.6. We find glueball masses, and the string tension to be roughly in the ratio m (2 − ): m (0 − ): m (2 + ): m (0 + ):√ K ≈7:6.5:5.5:3.8:1 for the smallest lattice spacings.- GAUGE FIELD THEORY: SU(2)
