On the Existence of the Coleman Instantons
arXiv:2104.12661 · doi:10.1088/1475-7516/2021/10/066
Abstract
We identify infinite classes of potentials for which the Coleman instantons do not exist. For these potentials, the decay of a false vacuum must be described by the new instantons introduced in [7,8].
