  We study the Landau gauge propagators of the lattice SU(2) 3d adjoint Higgs
model, considered as an effective theory of high temperature 4d SU(2) gauge
theory. From the long distance behaviour of the propagators we extract the
screening masses. It is shown that the pole masses extracted from the
propagators agree well with the screening masses obtained recently in finite
temperature SU(2) theory. The relation of the propagator masses to the masses
extracted from gauge invariant correlators is also discussed. In so-called
lambda gauges non-perturbative evidence is given for the gauge independence of
pole masses within this class of gauges.
