Reconsidering the calculation of the false vacuum decay rate at zero temperature

Abstract

In the calculation of the decay rate at finite temperature using the saddle point approximation, we identified some inconsistencies in the calculation of the decay rate at zero temperature. These inconsistencies may impact the explanation provided by Callan and Coleman. To address these inconsistencies, we recalculated the decay rate using the shifted-bounce solution and the shot solution.
