Examples of N=2 to N=1 supersymmetry breaking

Understand

In this paper we consider gauged N=2 supergravities which arise in the low-energy limit of type II string theories and study examples which exhibit spontaneous partial supersymmetry breaking.

• For the quantum STU model we derive the scalar field space and the scalar potential of the N=1 supersymmetric low-energy effective action.
• We also study the properties of the Minkowskian N=1 supersymmetricground states for a broader class of supergravities including the quantum STU model.
