Double copy structure of parity-violating CFT correlators

A bstract We show that general parity-violating 3d conformal field theories a double copy structure for momentum space 3-point functions of conserved currents, stress tensor and marginal scalar operators. Splitting up the CFT correlator into two parts — called homogeneous non-homogeneous we relations exist each part separately. arrive at similar conclusions regarding structures using tree-level correlators massless fields in dS 4 . also discuss flat limit these correlators. further extend analysis to involving higher-spin which suggests spin- s current can be thought as copies spin one correlator.
