Abstract
Cluster expansion methods are applied to theSU(2) lattice gauge model in (2+1) dimensions. Strong-coupling series are calculated for the vacuum energy per site, the axial string tension, and the scalar mass gap; while ELCE approximants are used to estimate the string tension beyond its roughening transition. The simple scaling behaviour expected of this super-renormalizable theory is clearly seen, and we estimate that in the continuum limit the string tension σ∼(0.14±0.01)g 4, while the mass gapM s ∼(2.2±0.25)g 2. More accurate Monte Carlo simulations are needed to check the universality between the Hamiltonian and Euclidean versions of this model.
