Asymptotic Four Point Functions

Understand

We initiate the study of four-point functions of large BPS operators at any value of the coupling.

• We do it by casting it as a sum over exchange of superconformal primaries and computing the structure constants using integrability.
• Along the way, we incorporate the nested Bethe ansatz structure to the hexagon formalism for the three-point functions and obtain a compact formula for the asymptotic structure constant of a non-BPS operator in a higher rank sector.
