Towards the higher point holographic momentum space amplitudes

Abstract

In this paper, we calculate higher point tree level vector amplitudes propagating in AdS${}_4$. We use bulk perturbation theory to compute tree level Witten diagrams. We show that when these amplitudes are written in momentum space, they reduce to relatively simple expressions. We explicitly compute four and five point correlators and also sketch a general strategy to compute the full six-point correlators.
