Abstract

In contrast to the complex ϕ4 model, vortex-antivortex collisions in the complex ϕ6 theory reveal a resonant structure due to the existence of a remarkably stable, long-lived, large-amplitude oscillon in the broken vacuum. Surprisingly, it persists despite the absence of a mass gap associated with the flat direction in the broken vacuum. We demonstrate that its existence is related to a far-distance modification of the potential, namely, the appearance of an unbroken (false or true) vacuum.
