- We study the approach to the continuum limit of SU(2) lattice gauge theory by accurately calculating several physical quantities on lattices up to 204 and for couplings up to β=4/g2=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 g2 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. © 1987.
