Temperatures are assumed to be much greater than the inverse of the nucleation radius. The value of a local minimum of the scalar potential is arbitrary. Thus, both true and false vacuua may have arbitrary cosmological constants.5 pages 1 FigureHigh Energy Physics - TheoryAstrophysicsHigh Energy Physics - Phenomenologytext
