Complex Factorisation and Recursion for One-Loop Amplitudes
Sam D. Alston, David C. Dunbar, Warren B. Perkins
We consider the factorisation of one-loop amplitudes at complex kinematic points. By determining the terms that are absent for real kinematics, we can construct a recursive ansatz…

Constructing Gravity Amplitudes from Real Soft and Collinear Factorisation
David C. Dunbar, James H. Ettle, Warren B. Perkins
Soft and collinear factorisations can be used to construct expressions for amplitudes in theories of gravity. We generalise the "half-soft" functions used previously to "soft-lifti…
