A Unified View of Vacuum Decay Channels

Abstract

The tunneling potential formalism, an alternative to the standard Coleman Euclidean approach, offers in a natural way a unified view of vacuum decays. In particular, I show in this talk how Coleman's bounce is just a member of a continuous family of solutions that can also feature Hawking-Moss instantons, pseudo-bounces and bubble-of-nothing solutions.
