Abstract
Abstract
We consider $$ \mathcal{N} $$
N
= 1 superconformal field theories in four dimensions possessing an additional conserved spinor current multiplet Sα and study three-point functions involving such an operator. A conserved spinor current multiplet naturally exists in superconformal theories with $$ \mathcal{N} $$
N
= 2 supersymmetry and contains the current of the second supersymmetry. However, we do not assume $$ \mathcal{N} $$
N
= 2 supersymmetry. We show that the three-point function of two spinor current multiplets and the $$ \mathcal{N} $$
N
= 1 supercurrent depends on three independent tensor structures and, in general, is not contained in the three-point function of the $$ \mathcal{N} $$
N
= 2 supercurrent. It then follows, based on symmetry considerations only, that the existence of one more Grassmann odd current multiplet in $$ \mathcal{N} $$
N
= 1 superconformal field theory does not necessarily imply $$ \mathcal{N} $$
N
= 2 superconformal symmetry.
