Abstract: We compute correlation functions of two local operators and one defect in holographic conformal field theories. In the supergravity description, the local operators are dual to certain Kaluza-Klein modes, while the defects are dual to probe branes preserving part of the supersymmetry. For concreteness, this talk focuses on correlators of two chiral-primary operator and one Maldacena-Wilson line in N=4 SYM. To obtain the leading strong-coupling correction to this correlator, we make an ansatz in terms of Witten diagrams and fix it with the help of superconformal Ward identities and localization. The result admits a closed-form expression, which takes a surprisingly simple form in Mellin space. Link to the Event Video |
