Hunting for Dynamical Supersymmetry Breaking in Theories That S-confine

TL;DR

This paper explores how perturbing certain well-understood s-confining supersymmetric gauge theories can lead to models exhibiting dynamical supersymmetry breaking with stable vacua, providing new insights into SUSY-breaking mechanisms.

Contribution

The authors construct simple models of dynamical supersymmetry breaking by perturbing specific s-confining SU(N) theories with a single trilinear operator, revealing new SUSY-breaking vacua.

Findings

Stable vacua with spontaneous SUSY breaking identified.

Calculable properties in some models, non-calculable in others.

Perturbations induce SUSY-breaking in well-understood theories.

Abstract

The s-confining theories are a class of supersymmetric gauge theories with infrared dynamics which are well-understood. Perturbing such theories can give rise to dynamical supersymmetry breaking. We realize simple models of dynamical supersymmetry breaking by perturbing two of the 10 SU(N) s-confining gauge theories by a single trilinear operator. These examples have locally stable vacua with spontaneous supersymmetry breaking. The first is SU(5) with two generations (consisting of an antisymmetric tensor and an antifundamental) plus two flavors. The second is SU(5) with three generations. The properties of the former vacuum are calculable while those of the latter vacuum are not. We briefly discuss the other SU(N) models.
