Some properties of meta-stable supersymmetry-breaking vacua in Wess-Zumino models

TL;DR

This paper investigates the general properties of meta-stable supersymmetry-breaking vacua in Wess-Zumino models, highlighting degeneracy, coupling constraints, and presenting a model with a long-lived vacuum, with extensions to non-renormalizable models.

Contribution

It provides new insights into the structure and stability of supersymmetry-breaking vacua in Wess-Zumino models, including a simple example of a long-lived meta-stable vacuum.

Findings

Tree-level degeneracy is a generic feature.

Constraints on couplings influence vacuum stability.

A simple model with a long-lived meta-stable vacuum is presented.

Abstract

As a contribution to the current efforts to understand supersymmetry-breaking by meta-stable vacua, we study general properties of supersymmetry-breaking vacua in Wess-Zumino models: we show that tree-level degeneracy is generic, explore some constraints on the couplings and present a simple model with a long-lived meta-stable vacuum, ending with some generalizations to non-renormalizable models.
