New Phases in O'Raifeartaigh-like Models and $R$-symmetry Breaking

Understand

We study $\mathcal{N}=1$ models in which supersymmetry and $R$-symmetry are broken spontaneously.

• We find that even the simplest well-known O'Raifeartaigh-like models exhibit previously unnoticed phases and dynamics.
• D-terms play an important role in the dynamics, creating a runaway behavior at tree-level which is stabilized radiatively at a large scale.
• This leads to a dynamically-generated hierarchy of scales.
