Simplicity of AdS Supergravity at One Loop
Luis F. Alday, Xinan Zhou
We demonstrate the simplicity of IIB supergravity at one loop level, by studying non-planar holographic four-point correlators in Mellin space. We develop a syste…
A Basis of Analytic Functionals for CFTs in General Dimension
Dalimil Mazac, Leonardo Rastelli, Xinan Zhou
We develop an analytic approach to the four-point crossing equation in CFT, for general spacetime dimension. In a unitary CFT, the crossing equation (for, say, the s- and t-channel…
Five-Point Function from Supergravity
Vasco Gonçalves, Raul Pereira, Xinan Zhou
We develop new techniques to compute five-point correlation functions from IIB supergravity on . Our methods rely entirely on symmetry and general consistency cond…
Tree-Level Correlators: Hidden Six-Dimensional Conformal Symmetry
Leonardo Rastelli, Konstantinos Roumpedakis, Xinan Zhou
We revisit the calculation of holographic correlators in . We develop new methods to evaluate exchange Witten diagrams, resolving some technical difficulties that prevent a…
