  The effective action describing the long range fluctuations in the high
temperature phase of the electroweak standard theory is a strongly coupled
SU(2)-Higgs-model in three dimensions. We outline in detail a model in which
the spatial correlation scales in this phase are calculated as inverse
relativistic bound state masses. Selection rules for these states are derived.
The correlation masses are calculated by evaluating the bound state Green's
function. The scalar-scalar-potential and its influence on the masses is
investigated. The predictions for the correlation masses agree very well with
the lattice data available now.
