Asymptotic infrared fractal structure of the propagator for a charged fermion
It is well known that the long-range nature of the Coulomb interaction makes the definition of asymptotic “in” and “out” states of charged particles problematic in quantum field theory. In particular, the notion of a simple particle pole in the vacuum charged particle propagator is untenable and sho...
