Metastable Rank-Condition Supersymmetry Breaking in a Chiral Example

TL;DR

This paper explores a chiral model extension of ISS vacua, demonstrating a metastable supersymmetry-breaking vacuum with stabilized pseudo-moduli and unbroken R-symmetry, providing insights into R-symmetry breaking mechanisms.

Contribution

It presents a detailed example of a chiral, s-confining theory that reduces to ISS-like sectors, highlighting a metastable vacuum with all pseudo-moduli stabilized and unbroken R-symmetry.

Findings

The model exhibits a metastable supersymmetry-breaking vacuum.

All pseudo-moduli are stabilized at the origin.

The R-symmetry remains unbroken in the vacuum.

Abstract

We discuss generalizations of Intriligator-Seiberg-Shih (ISS) vacua to chiral models. We study one example, of an s-confining theory, in detail. In the IR, this example reduces to two ISS-like sectors, and exhibits a supersymmetry-breaking vacuum with all pseudo-moduli stabilized at the origin, and with the R-symmetry unbroken. The IR theory is interesting from the point of view of R-symmetry breaking. This theory is an O'Raifeartaigh model with all charges zero or two, but the presence of a second R-charged pseudo-modulus with superpotential couplings to the messengers in principle allows for R-symmetry breaking.
