The Universe out of an Elementary Particle?

TL;DR

This paper models elementary particles as 2+1 dimensional branes in 3+1 dimensions, exploring their stability, quantum decay, and potential to form an infinite universe, linking particle physics with cosmology.

Contribution

It introduces a novel brane-based model of elementary particles that incorporates gauge fields, surface tension, and vacuum energy, analyzing their stability and decay into a universe.

Findings

Stable particle configurations can exist with gauge fields and surface tension.

Vacuum energy inside the brane can lead to quantum decay into an infinite universe.

Quantum boundary conditions influence the stability and decay processes.

Abstract

We consider a model of an elementary particle as a 2 + 1 dimensional brane evolving in a 3 + 1 dimensional space. Introducing gauge fields that live in the brane as well as normal surface tension can lead to a stable "elementary particle" configuration. Considering the possibility of non vanishing vacuum energy inside the bubble leads, when gravitational effects are considered, to the possibility of a quantum decay of such "elementary particle" into an infinite universe. Some remarkable features of the quantum mechanics of this process are discussed, in particular the relation between possible boundary conditions and the question of instability towards Universe formation is analyzed.
