Abstract
I will discuss a recently introduced approach to the study of non-protected observables in N=4 SYM.
The idea - dubbed Bootstrability - is to combine exact information from Integrability (which for us will mean data on the spectrum) with the constraints of the Conformal Bootstrap. Integrability data on the spectrum help to focus on a point in theory space and lead to much narrower bounds for the OPE coefficients.
I will describe the first applications of this idea in the case of the line defect CFT living on a supersymmetric Wilson line in the 4D gauge theory.
In particular, I describe two different strategies to incorporate information from integrability in the bootstrap - first through data on the spectrum of physical operators, and then through data on deformations, such as the deformation associated with bending the WIlson line to form a cusp. In the last part of the talk, I will discuss ongoing work which includes new bootstrap strategies.
