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…

In conformal field theories (CFTs) of dimension d > 3, two-dimensional (2d) conformal defects are characterised in part by central charges defined via the defect’s contribution to the trace anomaly.
