Angular intricacies in hot gauge field theories
arXiv:hep-ph/0304023 · doi:10.1063/1.1814418
Abstract
It is argued that in hot gauge field theories, "Hard Thermal Loops" leading order calculations call for a definite sequence of angular averages and discontinuity (or Imaginary part prescription) operations, and run otherwise into incorrect results. The ten years old collinear singularity problem of hot , provides a striking illustration of that fate.
