Query: Confinement in Three Dimensions and the Electroweak Phase Transition   The infrared behaviour of the standard model at finite temperature is
determined by the confining phase of the SU(2)-Higgs model in three dimensions.
Due to the Landau singularity of the three-dimensional gauge theory the
perturbative treatment of the electroweak phase transition breaks down for
Higgs masses above a critical mass $m_H^c$. Based on a renormalization group
improved effective potential we find $m_H^c\sim$ 70 GeV. The scalar
self-coupling has a Landau-type singularity also in the abelian U(1)-Higgs
model, which leads to a breakdown of perturbation theory in the symmetric
phase.
