More on renormalizable exceptions to Nelson-Seiberg theorem

Abstract

The Nelson-Seiberg theorem dictates conditions for the spontaneous breaking of the supersymmetry in Wess–Zumino models with generic, possibly nonrenormalizable, superpotential; the existence of the R-symmetry is necessary while the spontaneous breaking of the R-symmetry is sufficient. If we restrict ourselves to generic but renormalizable theories, however, there exist Wess–Zumino models whose vacua break the R-symmetry spontaneously while preserving the supersymmetry. The classification and conditions of such renormalizable exceptions are under active study. We give some new examples of spontaneous breaking of the R-symmetry with preserved supersymmetry that are not covered in the literature.
