Super-Higgs in Superspace

arXiv:1201.4537

Abstract

We determine the effective gravitational couplings in superspace whose components reproduce the supergravity Higgs effect for the constrained Goldstino multiplet. It reproduces the known Gravitino sector whilst constraining the off-shell completion. We show that these components arise by computing the effective action. This may be useful for phenomenological studies and model building: We give an example of its application to multiple Goldstini.
