Abstract
Coupled 1-loop gap equations are studied numerically for non-Abelian
electric and magnetic screening in various versions of the
three-dimensional effective gauge models. Corrections due to higher
dimensional and non-local operators are assessed quantitatively.
Comparison with numerical Monte-Carlo investigations suggests that
quantitative understanding beyond the qualitative features can be
achieved only by going beyond the present treatment.
