Abstract

We evaluate both the vacuum decay rate at zero temperature and the finite temperature nucleation rate for the [Formula: see text] model. Using the thin-wall approximation, we obtain the bounce solution for the model and we were also able to give the approximate eigenvalue equations for the bounce.
