MHV diagrams in momentum twistor space

We show that there are remarkable simplifications when the MHV diagram formalism for$ \mathcal{N} = 4 $ super Yang-Mills is reformulated in momentum twistor space. The vertices are replaced by unity while each propagator becomes a dual superconformal ‘R-invariant’ whose arguments may be read off fro...
