SIMIS Seminar on Field Theory and String Theory: Defect Two-point Functions in 6d (2,0) Theories

Speaker: Xinan Zhou (Kavli ITS, UCAS & ShanghaiTech University)

Abstract: 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 contribution corresponds to sums of tree-level Witten diagram in AdS7×S4 in the presence of an AdS3 defect. I will show that these correlators can be uniquely determined by imposing only superconformal symmetry and consistency conditions, 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.
