Three-point functions of a superspin-2 current multiplet in 3D, N=1 superconformal theory

Abstract

We consider $\mathcal{N}=1$ superconformal field theories in three-dimensions possessing a conserved current multiplet ${\mathcal{F}}_{({\alpha }_1{\alpha }_2{\alpha }_3{\alpha }_4)}$ 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 $\mathcal{F}$, focusing particularly on the three-point function $⟨\mathcal{FFF}⟩$. 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.
