Momentum space CFT correlators of non-conserved spinning operators
Raffaele Marotta, Kostas Skenderis, Mritunjay Verma
We analyse the 3-point CFT correlators involving non-conserved spinning operators in momentum space. We derive a general expression for the conformal Ward identities defining the 3…
Position-Space Renormalisation of the Energy-Momentum Tensor
Henrique Bergallo Rocha, Luigi Del Debbio, Andreas Jüttner +4
There is increasing interest in the study of nonperturbative aspects of three-dimensional quantum field theories (QFT). They appear as holographic dual to theories of (strongly cou…
An embedding formalism for CFTs in general states on curved backgrounds
Enrico Parisini, Kostas Skenderis, Benjamin Withers
We present a generalisation of the embedding space formalism to conformal field theories (CFTs) on non-trivial states and curved backgrounds, based on the ambient metric of Fefferm…
Bulk renormalization and the AdS/CFT correspondence
Máximo Bañados, Ernesto Bianchi, Iván Muñoz +1
We develop a systematic renormalization procedure for QFT in anti-de Sitter spacetime. UV infinities are regulated using a geodesic point-splitting method, which respects AdS isome…
A handbook of holographic 4-point functions
Adam Bzowski, Paul McFadden, Kostas Skenderis
We present a comprehensive discussion of tree-level holographic -point functions of scalar operators in momentum space. We show that each individual Witten diagram satisfies the…
Renormalization of the scalar energy-momentum tensor using the Wilson flow
Joseph K. L. Lee, Luigi Del Debbio, Elizabeth Dobson +6
In the holographic approach to cosmology, cosmological observables are described in terms of correlators of a three-dimensional boundary quantum field theory. As a concrete model,…
