KERNEL OF THE CLASSICAL ZITTERBEWEGUNG

Barut's classical zitterbewegung model includes the internal dynamical variables and the quantization of this system gives a general transit ion amplitude between the different space-time points and internal coo rdinates and momentum. It includes the transition amplitude between th e half integer and integer spin eigenvalues. Spin eigenfunctions lead to all sets of relativistic wave equations, as well as the Dirac equat ion.
