-point amplitudes with a single negative-helicity graviton
Sam D. Alston, David C. Dunbar, Warren B. Perkins
We construct an expression for the n-point one-loop graviton scattering amplitude with a single negative helicity external leg using an augmented recursion technique. We analyse th…

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…
