We present an ansatz for all one-loop amplitudes in pure Einstein gravity for which the n external gravitons have the same outgoing helicity. These loop amplitudes, which are rational functions of the momenta, also arise in the quantization of self-dual gravity in four-dimensional Minkowski space. Our ansatz agrees with explicit computations via D-dimensional unitarity cuts for n less than or equal to 6. It also has the expected analytic behavior, for all n, as a graviton becomes soft, and as two momenta become collinear. The gravity results are closely related to analogous amplitudes in (self-dual) Yang-Mills theory.

Collinear Corrections to the Cachazo-Strominger Soft Theorem
The sub-subleading soft graviton theorem gains collinear correction terms, derived from distributional spinor derivative identities and shown to agree with the collinear part of the asymptotic charges found by Freidel...
