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 …
