Abstract

We consider N=1\mathcal{N=1} superconformal field theories in three-dimensions possessing a conserved current multiplet F(α1α2α3α4)\mathcal{F}_{ (\alpha_{1} \alpha_{2} \alpha_{3} \alpha_{4}) } which we refer to as the superspin-2 current multiplet. At the component level it contains a conserved spin-2 current different from the energy-momentum tensor and a conserved fermionic higher spin current of spin 5/2. Using a superspace formulation, we calculate correlation functions involving F\mathcal{F}, focusing particularly on the three-point function FFF \langle \mathcal{F} \mathcal{F} \mathcal{F} \rangle . After imposing the constraints arising from conservation equations and invariance under permutation of superspace points, we find that the parity-even and parity-odd sectors of this three-point function are each fixed up to a single coefficient. The presence of the parity-odd contribution is rather non-trivial, as there is an apparent tension between supersymmetry and the existence of parity-odd structures.
