The Holographic Goldstino

Understand

We find the fingerprints of the Goldstino associated to spontaneous supersymmetry breaking in a prototype holographic model for a strongly coupled field theory.

• The Goldstino massless pole arises in two-point correlators of the supercurrent, due to contact terms in supersymmetry Ward identities.
• We show how these contact terms are obtained from the holographic renormalization of the gravitino sector, independently of the details of the bulk background solution.
• For completeness, we provide an example of a family of such solutions in a simple supergravity model.
