Résumé |
We present a systematic way of constructing holographic effective descriptions of strongly coupled gauge
theories which break supersymmetry. We set ourselves in an N=2 gauged SUGRA with a minimal content in
order to reproduce a dual N = 1 effective SCFT which has a U(1)R symmetry and a chiral operator whose
components are responsible for triggering the RG flow. The generic backgrounds being singular, one can
still extract information about the dual RG flows by computing two point correlators via holographic
renormalization. We will pay special attention to the appearance of massless modes, such as the dilaton,
the R-axion and the Goldstino when the respective symmetries are spontaneously broken, and their lifting
when the breaking is explicit. We finally comment on the application of SUSY-breaking holographic
backgrounds as archetypes of strongly coupled hidden sectors for gauge mediation of supersymmetry
breaking. |
