BCFW recursion
From Infogalactic: the planetary knowledge core
The Britto–Cachazo–Feng–Witten recursion relations are a set of on-shell recursion relations in quantum field theory.[1][2] They are named for their creators, Ruth Britto, Freddy Cachazo, Bo Feng and Edward Witten.
The BCFW recursion method is a way of calculating scattering amplitudes.[3] Extensive use is now made of these techniques.[4]
