...Aiming at the unitary and parity preserving higher-spin theory in flat space we reconstruct the part of the quartic Hamiltonian that contains self-interactions of the scalar field, which can be regarded as the flat space counterpart of the AdS4 result [37, 38]....

...This result is consistent with observations in the literature [62, 95] for lower-spin exchanges, that an exchange Witten diagram does not simply correspond in the CFT to the exchange of the operator dual to the exchanged bulk field: There are additional contributions from doubletrace operators built from the single-trace operators that are dual to the external fields of the exchange Witten diagram....
