The Dirac Propagator From Pseudoclassical Mechanics #
Theodore J. Allen ##
California Institute of Technology, Pasadena, CA 91125
Abstract
In this note it is demonstrated that the unitary propagator is obtained from the
pseudoclassical system proposed as a first­quantized version of the Dirac particle by
Berezin and Marinov. The action for the system is written in a form which has
manifest global supersymmetry on the worldline.

1. Introduction
Little is known of the point particle versions of quantum field theories while
much is known about quantum field theories. On the other hand, string theories are
