Spinning loop amplitudes in anti–de Sitter space
In this work we present a systematic study of AdSd+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...

Zusammenfassung: | In this work we present a systematic study of AdSd+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. |
