Abstract
We study to what extent the three-dimensional SU(N) + adjoint Higgs theory can be used as an effective theory for finite-temperature SU(N) gauge theory, with N = 2,3. The parameters of the 3d theory are computed in 2-loop perturbation theory in terms of T/Lambda(<(MS)over bar>), N and N-f. The perturbative effective potential of the 3d theory is computed to two loops for N = 2. While the Z(N) symmetry probably driving the 4d confinement-deconfinement phase transition (for N-f = 0) is not explicit in the effective Lagrangian, it is partly reinstated by radiative effects in the 3d theory, Lattice simulations in the 3d theory are carried out for N = 2, and the static screening masses relevant for the high-temperature phase of the 4d theory are measured, In particular, we measure non-perturbatively the O(g(2)T) correction to the Debye screening mass, We find that non-perturbative effects are much larger in the SU(2) + adjoint Higgs theory than in the SU(2) + fundamental Higgs theory, (C) 1997 Elsevier Science B.V.
