Tree-level Correlators of scalar and vector fields in AdS/CFT

Understand

Extending earlier results by Paulos, we discuss further the use of the embedding formalism and Mellin transform in the calculation of tree-level correlators of scalar and vector fields in AdS/CFT.

• We present an iterative procedure that builds amplitudes by sewing together lower-point off-shell diagrams.
• Both scalar and vector correlators are shown to be given in terms of Mellin amplitudes.
• We apply the procedure to the explicit calculation of three-, four- and five-point correlators.
