Metastable Vacua in Superconformal SQCD-like Theories

TL;DR

This paper investigates how to achieve stable, long-lived metastable vacua in superconformal SQCD-like theories by deforming the superpotential and analyzing the RG flow to control couplings.

Contribution

It introduces specific superpotential deformations that stabilize non-supersymmetric vacua in superconformal theories, enabling controlled long-lived metastable states.

Findings

Deformations stabilize non-supersymmetric vacua.

RG analysis constrains physical couplings for longevity.

Long-lived metastable vacua are achievable in these models.

Abstract

We study dynamical supersymmetry breaking in vector-like superconformal N=1 gauge theories. We find appropriate deformations of the superpotential to overcome the problem of the instability of the non supersymmetric vacuum. The request for long lifetime translates into constraints on the physical couplings which in this regime can be controlled through efficient RG analysis.
