Abstract

We propose a new gauge prepotential ϒ_i describing the four-dimensional N=2 superconformal gravitino multiplet. The former naturally arises via a superspace reduction of the N=3 conformal supergravity multiplet. A locally superconformal chiral action for ϒ_i, which is gauge-invariant in arbitrary conformally flat backgrounds, is derived. This construction readily yields a new superprojector, which maps an isospinor superfield Ψ_i to a multiplet characterised by the properties of a conformal supercurrent associated with ϒ_i. Our main results are also specialised to N=2 anti-de Sitter superspace.
