Dispersion Formulas in QFTs, CFTs, and Holography
David Meltzer
We study momentum space dispersion formulas in general QFTs and their applications for CFT correlation functions. We show, using two independent methods, that QFT dispersion formul…
On duality of color and kinematics in (A)dS momentum space
Soner Albayrak, Savan Kharel, David Meltzer
We explore color-kinematic duality for tree-level AdS/CFT correlators in momentum space. We start by studying the bi-adjoint scalar in AdS at tree-level as an illustrative example.…
Model-Dependence of Minimal-Twist OPEs in Holographic CFTs
A. Liam Fitzpatrick, Kuo-Wei Huang, David Meltzer +2
Following recent work on heavy-light correlators in higher-dimensional conformal field theories (CFTs) with a large central charge , we clarify the properties of stress tensor…
The Lorentzian inversion formula and the spectrum of the 3d O(2) CFT
Junyu Liu, David Meltzer, David Poland +1
We study the spectrum and OPE coefficients of the three-dimensional critical O(2) model, using four-point functions of the leading scalars with charges 0, 1, and 2 (, , and $…
The Inversion Formula and 6j Symbol for 3d Fermions
Soner Albayrak, David Meltzer, David Poland
In this work we study the symbol of the conformal group for fermionic operators. In particular, we study 4-point functions containing two fermions and two scalars and als…
Unitarity Methods in AdS/CFT
David Meltzer, Eric Perlmutter, Allic Sivaramakrishnan
We develop a systematic unitarity method for loop-level AdS scattering amplitudes, dual to non-planar CFT correlators, from both bulk and boundary perspectives. We identify cut ope…
