Scientific paper

The effect of perturbative infrared singularities on the finite-temperature effective potential in the standard model with a light Higgs boson is investigated. Together with the Coleman-Weinberg term, it promotes the full-gauge-symmetry breaking. The transition to the U(1) vacuum via quantum tunneling is expected to occur at some temperature near 100 MeV. However, without knowledge of dynamical details, one cannot conclusively decide whether the chiral or the (full) gauge symmetry breaks first.
