Abstract
If a first-order phase transition is terminated by percolation and col lisions of new-phase bubbles, there will exist a period of nonequilibr ium between the time bubbles collide and the time thermal equilibrium is established. We study the behavior of the order parameter during th is phase. We find that large nonthermal fluctuations at this stage red uce the order parameter below its eventual thermal equilibrium value. We comment on possible consequences for electroweak baryogenesis. [S05 56-2821(97)04422-6].
