“…This result relies on the technical assumption that (G − 1) vanishes in the u-channel collinear limit even on the second sheet, which has never been rigorously proven[44,58]. However, we do not expect this assumption to affect the results of the present paper, as long as the right-hand-side can be computed from the EFT correlator 10.…”

“…A distinct advantage of the CFT approach to AdS theories is that it is fully rigorous. The requisite analyticity and causality properties of the four-point correlator are direct consequences of the bootstrap axioms (see [44] for a recent discussion of how Lorentzian CFT axioms follow from the standard Euclidean axioms), while boundedness in the Regge limit (with Regge intercept ≤ 1) is a consequence of unitarity and the OPE at the non-perturbative level [16].…”

“…Many implicit assumptions made in QFTs are on firmer footing in CFTs (eg. [45]) and as such lessons from CFTs will be useful guiding beacons for QFTs. Since the crossing symmetric dispersion relation was set up for CFT Mellin amplitudes in [46], a reasonably straightforward extension of the methods set up in this paper should be possible.…”

“…Although the case of non-unitary CFTs has not been rigorously established, it is reasonable to assume that they share some similarities based on the 2d examples. See [75,76] for recent discussions of the OPE convergence in the distributional sense and in Minkowski space. 18 Introducing more conformal blocks can cancel out some part of the small difference in a subregion.…”
