Abstract
We apply the linear expansion to non-Abelian gauge theory on the lattice, with SU(2) as the gauge group. We establish an appropriate parametrization and evaluate the average plaquette energy to . As a check on our results, we recover the large- expansion up to , which involves some contributions. Using these contributions we construct a variant of the expansion which gives a good fit to the data down to the transition region.
