Bound states in the hot electroweak phase

Abstract The high temperature phase of the electroweak standard theory is described by a strongly coupled SU (2)-Higgs-model in three dimensions. As in the Abbott-Farhi-model Higgs and W -boson are low lying bound states. Using a method by Simonov based on the Feynman-Schwinger representation of correlators we calculate the masses of these states. Our results are compared with lattice masses.
