Towards the Gravituhedron: new expressions for NMHV gravity amplitudes
Abstract In this paper, we present new expressions for n-point NMHV tree-level gravity amplitudes. We introduce a method of factorization diagrams which is a simple graphical representation of R-invariants in Yang-Mills theory. We define the gravity analogues which we call G $$ \mathcal{G} $$ -invar...
