About the Coleman instantons in D dimensions

Year: 2022

Type: article

Abstract: We identify an infinite class of unbounded potentials for which the Coleman instantons do not exist in D-dimensional spacetime. For such potentials, the decay of a false vacuum is described by the new instantons introduced in [5], [6], [4]. For each spacetime dimension D, we also construct the two different classes of potentials for which the instanton equations are exactly solvable.
