Surface operators are among the most important observables of the 6d N $$ \mathcal{N} $$ = (2 , 0) theory. Here we apply the tools of defect CFT to study local operator insertions into the 1 / 2-BPS plane. We first relate the 2-point function of the displacement operator to the expectation value of the bulk stress tensor and translate this relation into a constraint on the anomaly coefficients associated with the defect. Secondly, we study the defect operator expansion of the stress tensor…
