Spinning loop amplitudes in anti–de Sitter space
Soner Albayrak, Savan Kharel
Abstract
In this work we present a systematic study of ${\mathrm{AdS}}_{d+1}$ loop amplitudes for gluons and gravitons using momentum space techniques. Inspired by the recent progress in tree-level computation, we construct a differential operator that can act on a scalar factor in order to generate gluon and graviton loop integrands: this systematizes the computation for any given loop level Witten diagram. We then give a general prescription in this formalism, and discuss it for bubble, triangle, and box diagrams.
