Abstract
The authors apply bootstrap methods to the half-BPS Wilson line with local operator insertions (defects) in the four-dimensional maximally supersymmetric (N = 4) Yang-Mills theory. They extract analitically the scaling dimension of the lightest non-protected scalar operator to the fourth order in the strong coupling expansion (t'Hooft coupling).
