From 4d ambitwistor strings to on shell diagrams and back
Abstract We investigate the relation between 4d ambitwistor string theory and on-shell diagrams for planar N = 4 $$ \mathcal{N}=4 $$ super-Yang-Mills and N = 8 $$ \mathcal{N}=8 $$ supergravity, and deduce several new results about their scattering amplitudes at tree-level and 1-loop. In particular,...
