Effects of Gravity and Finite Temperature on the Decay of the False Vacuum
Abstract
Description
I have calculated the exponential suppression factor in the decay rate of the false vacuum (per unit volume) for a real scalar field at finite temperature, in the presence of gravity, in the thin-wall approximation. 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.
