N = 7 On-shell diagrams and supergravity amplitudes in momentum twistor space
(2021)
Journal Article
We derive an on-shell diagram recursion for tree-level scattering amplitudes in N = 7 supergravity. The diagrams are evaluated in terms of Grassmannian integrals and momentum twistors, generalising previous results of Hodges in momentum twistor space...
