Abstract In this paper we use the spinor-helicity formalism to calculate 3-point functions involving scalar operators and spin-s conserved currents in general 3d CFTs. In spinor-helicity variables we notice that the parity-even and the parity-odd parts of a correlator are related. Upon converting spinor-helicity answers to momentum space, we show that correlators involving spin-s currents can be expressed in terms of some simple conformally invariant conserved structures. This in particular… Expand
Three-point functions of a superspin-2 current multiplet in 3D, N=1 superconformal theory
We consider N = 1 superconformal field theories in three dimensions possessing a conserved current multiplet F(α1α2α3α4) which we refer to as the superspin–2 current multiplet. At the component levelExpand
