Farrow, Joseph A. and Lipstein, Arthur E. and McFadden, Paul (2019) 'Double copy structure of CFT correlators.', Journal of high energy physics., 2019 (02). p. 130.
We consider the momentum-space 3-point correlators of currents, stress tensors and marginal scalar operators in general odd-dimensional conformal field theories. We show that the flat space limit of these correlators is spanned by gauge and gravitational scattering amplitudes in one higher dimension which are related by a double copy. Moreover, we recast three-dimensional CFT correlators in terms of tree-level Feynman diagrams without energy conservation, suggesting double copy structure beyond the flat space limit.
