Structure Constants and Integrable Bootstrap in Planar N=4 SYM Theory

Understand

We introduce a non-perturbative framework for computing structure constants of single-trace operators in the N=4 SYM theory at large N.

• Our approach features new vertices, with hexagonal shape, that can be patched together into three- and possibly higher-point correlators.
• These newborn hexagons are more elementary and easier to deal with than the three-point functions.
• Moreover, they can be entirely constructed using integrability, by means of a suitable bootstrap program.
