A Simple Derivation of the Hard Thermal Loop Effective Action
arXiv:hep-th/9809013 · doi:10.1103/PhysRevD.59.045018
Abstract
We use the background field method along with a special gauge condition, to derive the hard thermal loop effective action in a simple manner. The new point in the paper is to relate the effective action explicitly to the S-matrix from the onset.
