title = "Integrability and conformal bootstrap: One dimensional defect conformal field theory",
abstract = "In this paper we study how the exact nonperturbative integrability methods in 4D N=4 super-Yang-Mills can work efficiently together with the numerical conformal bootstrap techniques to go beyond the spectral observables and access previously unreachable quantities such as correlation functions at finite coupling. In the setup of 1D defect conformal field theory living on a Maldacena-Wilson line, we managed to compute with good precision a nonsupersymmetric structure constant for a wide range of the {\textquoteleft}t Hooft coupling. Our result is particularly precise at strong coupling and matches well with the recent analytic results of Meneghelli and Ferrero.",
