## Abstract Quantum particles and classical particles are described in a common setting of classical statistical physics. The property of a particle being βclassicalβ or βquantumβ ceases to be a basic conceptual difference. The dynamics differs, however, between quantum and classical particles. We
Previous work relating the thermodynamic potential to elementary particle S-matrix elements is generalized and re-derived directly from the expressions for the diagrams of many body theory. The divergent physical region poles are shown to introduce energy derivatives of mass shell delta functions wh
