Meta-Stable Dynamical Supersymmetry Breaking Near Points of Enhanced Symmetry

TL;DR

This paper demonstrates that metastable supersymmetry breaking naturally occurs near enhanced symmetry points in gauge theory moduli spaces, with all mass scales generated dynamically and vacua stabilized through quantum effects.

Contribution

It introduces a new model combining dynamical supersymmetry breaking with an O'Raifeartaigh mechanism near symmetry points, with all parameters generated dynamically.

Findings

Metastable vacua arise near enhanced symmetry points.

Mass parameters, including the SUSY breaking scale, are dynamically generated.

Vacua stability results from a balance of quantum effects.

Abstract

We show that metastable supersymmetry breaking is generic near certain enhanced symmetry points of gauge theory moduli spaces. Our model consists of two sectors coupled by a singlet and combines dynamical supersymmetry breaking with an O'Raifeartaigh mechanism in terms of confined variables. All relevant mass parameters, including the supersymmetry breaking scale, are generated dynamically. The metastable vacua appear as a result of a balance between non-perturbative and perturbative quantum effects along a pseudo-runaway direction.
