A bstract We give a detailed account of the methods introduced in [1] to calculate
holographic four-point correlators in IIB supergravity on AdS 5× S 5. Our approach relies …

A bstract We propose and demonstrate a new use for conformal field theory (CFT) crossing
equations in the context of AdS/CFT: the computation of loop amplitudes in AdS, dual to non …

We introduce the AdS/CFT correspondence as a natural extension of QFT in a fixed AdS
background. We start by reviewing some general concepts of CFT, including the embedding …

We study conformal partial waves (CPWs) in Mellin space with totally symmetric external
operators of arbitrary integer spin. The exchanged spin is arbitrary, and includes mixed …

A bstract We present a universal treatment for imposing superconformal constraints on
Mellin amplitudes for SCFT d with 3≤ d≤ 6. This leads to a new technique to compute …

A bstract We revisit the calculation of holographic correlators for eleven-dimensional
supergravity on AdS 7× S 4. Our methods rely entirely on symmetry and eschew detailed …

It was argued recently that the holographic higher spin theory features non-local
interactions. We further elaborate on these results using the Mellin representation. The main …

In this paper we consider Witten diagrams at one loop in AdS space for scalar $\phi^ 3+\phi^
4$ theory. After using Schwinger parametrization to trivialize the space-time loop integration …

A bstract We define Mellin amplitudes for the fermion-scalar four point function and the
fermion four point function. The Mellin amplitude thus defined has multiple components each …

A bstract We consider the four-point function of the lowest scalar in the stress-energy tensor
multiplet in\(\mathcal {N}= 8\) ABJ (M) theory [1, 2]. At large central charge c T∼ N 3/2, this …
