Radiation reaction from QED    [PDF]

Anton Ilderton, Greger Torgrimsson

We derive radiation reaction directly from the S-matrix of QED. We identify the diagrams and processes contributing to recoil effects in the average momentum of a scattered electron and, in an explicit example, find exact agreement with classical electrodynamics in the limit h-bar goes to zero. Our results unify a number of disparate, previously reported approaches.
