A Note on MHV Amplitudes for Gravitons

Abstract

We show how the maximally helicity violating (MHV) scattering amplitudes for gravitons can be related to current correlators and vertex operators in twistor space. This is similar to what happens in Yang-Mills theory and raises the possibility of a direct twistor-string-like construction for $\mathcal{N}=8$ supergravity.
