✦ Synopsis
The existence of run-away solutions in classical and non-relativistic quantum electrodynamics is reviewed. It is shown that the less singular high energy behavior of relativistic spin 1 2 quantum electrodynamics precludes an analogous behavior in that theory. However, a Landau-like [1] anomalous pole in the photon propagation function or in the electron-massive photon foward scattering amplitude would generate a new run-away, characterized by an energy scale |tm e exp(1Â:). This contrasts with the energy scale |tm e Â: associated with the classical and non-relativistic quantum run-aways.
