The two-loop five-point amplitude in N $$ \mathcal{N} $$ = 8 supergravity

Abstract We compute the symbol of the two-loop five-point amplitude in N $$ \mathcal{N} $$ = 8 supergravity. We write an ansatz for the amplitude whose rational prefactors are based on not only 4-dimensional leading singularities, but also d-dimensional ones, as the former are insufficient. Our nove...
