RENORMALIZATION AND RADIATIVE-CORRECTIONS AT FINITE TEMPERATURE
Journal or Book Title
PHYSICAL REVIEW D
We discuss the renormalization prescription for fermions at finite temperature and describe the procedure for calculating radiative corrections. Novel features arise, such as a lack of explicit Lorentz invariance, 1/k2 singularities, and the absorption of soft photons from the background heat bath. The methods are illustrated by explicit calculation of the electron renormalization and the radiative corrections to H→e+e- (with H being spin zero) in finite-temperature QED.
