Description
We study classical radiation fields at next-to-leading order using the
methods of scattering amplitudes. The fields of interest to us are sourced when
two massive, point-like objects scatter inelastically, and can be computed from one-
loop amplitudes. The real and imaginary parts of the amplitudes play important
but physically distinct roles in the radiation field. We argue that the imaginary part
captures the effects of radiation reaction. This aspect of radiation reaction is directly
linked to cuts of one-loop amplitudes which expose Compton trees.
