AB  - We study the defect CFT associated with the half-BPS Wilson line in <i>N</i>=4 Super Yang-Mills theory in four dimensions. Using a perturbative bootstrap approach, we derive new analytical results for multipoint correlators of protected defect operators at large N and weak coupling. At next-to-next-to-leading order, we demonstrate that the simplest five- and six-point functions are fully determined by non-perturbative constraints - which include superconformal symmetry, crossing symmetry, and the pinching of operators to lower-point functions - as well as by a single integral, known as the train track integral. Additionally, we present new analytical results for the four-point functions 〈1122 〉 and 〈1212 〉.
