On-shell recursion and soft theorems for worldline quantum field theory
Nathan Castet, Vincent F. He
We derive a set of on-shell recursion relations for amplitudes in worldline quantum field theory (WQFT), an effective theory of gravity coupled to a massive worldline which is rele…

Generalized Unitarity Method for Worldline Field Theory
Vincent F. He, Julio Parra-Martinez
We present a generalized unitarity method for theories of point-particle worldlines coupled to gravity, analogous to that of scattering amplitudes in quantum field theory. This met…
