Abstract
We present a formalism to calculate the probability distribution funct ion of a scalar field coarse-grained over some spatial scales with a G aussian filter at finite temperature. As an application, we investigat e the role of subcritical fluctuations in the electroweak phase transi tion in the minimal standard model. It is concluded that the universe was in a mixed state of true and false vacua already at the critical t emperature. (C) 1998 Elsevier Science B.V.
