Evaluating Real Time Finite Temperature Feynman Amplitudes
arXiv:hep-ph/9908438 · doi:10.1103/PhysRevD.61.025011
Abstract
We construct a program to calculate Feynman amplitudes at finite temperature in the real time Keldysh formalism using the symbolic manipulation program {\it Mathematica}. As an example, the usefulness of this program is demonstrated by proving the finite temperature Ward identity for QED in a second order effective theory.
