Query: Constraints on Chiral Operators in N=2 SCFTs   We study certain higher-spin chiral operators in N=2 superconformal field
theories (SCFTs). In Lagrangian theories, or in theories related to Lagrangian
theories by generalized Argyres-Seiberg-Gaiotto duality ("type A" theories in
our classification), we give a simple superconformal representation theory
proof that such operators do not exist. This argument is independent of the
details of the superconformal index. We then use the index to show that if a
theory is not of type A but has an N=2-preserving deformation by a relevant
operator that takes it to a theory of this type in the infrared, the
ultraviolet theory cannot have these higher-spin operators either. As an
application of this discussion, we give a simple prescription to extract the
2a-c conformal anomaly directly from the superconformal index. We also comment
on how this procedure works in the holographic limit.
