The electron thermal propagator at p>>T: An entire function of p_{0}
arXiv:hep-ph/0309322 · doi:10.1103/PhysRevD.69.045006
Abstract
The retarded electron propagator S_{R}(p_{0},p) at high momentum p>>T was shown by Blaizot and Iancu to be an entire function of complex p_{0}. In this paper a specific form for S_{R}(p_{0},p) is obtained and checked by showing that its temporal Fourier transform S_{R}(t, p) has the correct behavior at large t. Potential infrared and collinear divergences from the emission of soft photons do not occur.
