Single-Sector Supersymmetry Breaking in Supersymmetric QCD

TL;DR

This paper develops calculable models of single-sector supersymmetry breaking using deformations of supersymmetric QCD, where some Standard Model particles are composites, linking flavor hierarchies with SUSY-breaking spectra.

Contribution

It introduces new, weakly coupled models of single-sector SUSY breaking based on deformed SQCD with gauged flavor groups, enabling explicit calculations.

Findings

Models explain Standard Model flavor hierarchies through composite particles.

Predictive correlation between Yukawa couplings and SUSY-breaking soft terms.

Models are calculable via weakly coupled Seiberg dual descriptions.

Abstract

We construct examples of single-sector supersymmetry breaking based on simple deformations of supersymmetric QCD with (weakly) gauged flavor group. These theories are calculable in a weakly coupled Seiberg dual description. In these models, some of the particles in the first two generations of quarks and leptons are composites of the same strong dynamics which leads to dynamical supersymmetry breaking. Such models can explain the hierarchies of Yukawa couplings in the Standard Model, in a way that predictively correlates with the spectrum of SUSY-breaking soft terms.
