On spinning loop amplitudes in Anti-de Sitter space
arXiv:2006.12540 · doi:10.1103/PhysRevD.103.026004
Abstract
In this work we present a systematic study of AdS 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.
