Recursion for Differential Cross-Section from the Optical Theorem
Vatsal Garg, Hojin Lee, Kanghoon Lee
We present a novel framework for computing differential cross-sections in quantum field theory using the optical theorem and loop amplitudes, circumventing the traditional method o…

The Schwarzschild Black Hole from Perturbation Theory to all Orders
Poul H. Damgaard, Kanghoon Lee
Applying the quantum field theoretic perturbiner approach to Einstein gravity, we compute the metric of a Schwarzschild black hole order by order in perturbation theory. Using recu…
