Three-point correlators of stress tensors in maximally-supersymmetric conformal theories in d=3 and d=6

F. Bastianelli, S. Frolov, A. A. Tseytlin

We consider free superconformal theories of n=8 scalar multiplet in d=3 and (2,0) tensor multiplet in d=6 and compute 2-point and 3-point correlators of their stress tensors. The r…
