SUMMARY:Defect two-point functions in 6d (2\,0) theories - Xinan Zhou (Bei

DESCRIPTION:In this talk\, I will discuss correlation functions in 6d (2\,
  0) theories of two 1/2-BPS operators inserted away from a 1/2-BPS surface
  defect. In the large central charge limit the leading connected contribut
 ion corresponds to sums of tree-level Witten diagram in AdS7×S4 in the pr
 esence of an AdS3 defect. I will show that these correlators can be unique
 ly determined by imposing only superconformal symmetry and consistency con
 ditions\, eschewing the details of the complicated effective Lagrangian. I
  will present the explicit result of all such two-point functions\, which 
 exhibits remarkable hidden simplicity.
