Metastable gauged O'Raifeartaigh

Understand

We study the possibility of obtaining metastable supersymmetry breaking vacua in a perturbative gauge theory without singlet fields, thus allowing for scenarios where a grand unified symmetry and supersymmetry are broken by the same sector.

• We show some explicit SU(5) examples.
• The minimal renormalizable example requires the use of two adjoints, but it is shown to inevitably lead to unwanted light states.
• We suggest various alternatives, and show that the viable possibilities consist of allowing for non-renormalizable operators, of employing four adjoints or of adding at least one field in a different representation.
