Solitons and instantons in vacuum stability: physical phenomena

TL;DR

This paper explores the phenomena of solitons and instantons in vacuum stability, linking theoretical models with experimental data, and proposing mechanisms for universe stability, matter-antimatter asymmetry, and implications for dark matter and energy.

Contribution

It introduces a new framework connecting solitons, instantons, and vacuum stability, incorporating space-time dimensions and providing insights into cosmological phenomena.

Findings

CERN experiments suggest our vacuum is stable.

A new mechanism involving space-time dimensions explains universe stability.

Proposes hypotheses relating to Dark Matter and Dark Energy.

Abstract

In a previous paper [JCAP06, 033 (2018)] we have proved that it is possible to have a stable false vacuum in a potential that is unbounded from below. In this paper we discuss the Physics related to our theoretical and numerical results. We show that the results of recent CERN experiments lead to the fact that our vacuum is safe. We present a new mechanism, where the space-time dimension plays an important role, that explains why our Universe is stable. We provide new evidence that supports a process for the origin of matter-antimatter asymmetry recently introduced by other scientists. We examine confinement in the context of escape problems. We discuss multiverse, string theory landscape, and extra-dimensions using our framework. Finally, we use our solutions to introduce some hypotheses about Dark Matter and Dark Energy.
