Scientific paper

The consequences for cosmology of a Coleman-E. Weinberg light Higgs boson are considered. If SU(2) × U(1) symmetry breaking is induced by such a boson, the early universe went far out of equilibrium at the time of the SU(2) × U(1) phase transition. The universe supercooled far below the equilibrium transition temperature. The decay of the unstable vacuum, when it finally occured, was induced by a process of ``dynamical symmetry breaking'' and increased the entropy to baryon ratio of the universe by a factor of 105 or 106. (Related matters have been treated in recent work by Guth and E. Weinberg.)
