Dynamical completions of generalized O'Raifeartaigh models

TL;DR

This paper constructs gauge theory completions of generalized O'Raifeartaigh models that break supersymmetry and R-symmetry, allowing for flexible gaugino mass generation in gauge mediation.

Contribution

It introduces simple deformations of generalized ITIY models with gauge group Sp(N), producing effective models with stable pseudomoduli spaces and varied gaugino mass suppression.

Findings

Models can have locally stable pseudomoduli space near or away from the origin.

Effective models enable either suppressed or unsuppressed gaugino masses.

Gauge theory completions realize supersymmetry breaking with R-symmetry breaking.

Abstract

We present gauge theory completions of Wess-Zumino models admitting supersymmetry breaking vacua with spontaneously broken R-symmetry. Our models are simple deformations of generalized ITIY models, a supersymmetric theory with gauge group Sp(N), N+1 flavors plus singlets, with a modified tree level superpotential which explicitly breaks (part of) the global symmetry. Depending on the nature of the deformation, we obtain effective O'Raifeartaigh-like models whose pseudomoduli space is locally stable in a neighborhood of the origin of field space, or in a region not including it. Hence, once embedded in direct gauge mediation scenarios, our models can give low energy spectra with either suppressed or unsuppressed gaugino mass.
