  The complete set of static screening masses is determined for the SU(2) Higgs
model from one-loop coupled gap equations. Results from the version, containing
scalar fields both in the fundamental and adjoint representations are compared
with the model arising when the integration over the adjoint scalar field is
performed. A non-perturbative and non-linear mapping between the couplings of
the two models is proposed, which exhibits perfect decoupling of the heavy
adjoint scalar field. Also the alternative of a gauge invariant mass
resummation is investigated in the high temperature phase.
