The electron thermal propagator at p>>T: An entire function of p0
Abstract
The retarded electron propagator SR(p0,p) at high momentum p>>T was shown by Blaizot and Iancu to be an entire function of complex p0. In this paper a specific form for SR(p0,p) is obtained and checked by showing that its temporal Fourier transform SR(t, p) has the correct behavior at large t. Potential infrared and collinear divergences from the emission of soft photons do not occur.
