Klein-Gordon-Dirac equation: physical justification and quantization attempts
This paper concerns the Klein-Gordon-Dirac equation. A general solution of this equation, as a superposition of two Dirac plane harmonic waves with different masses has been obtained. The multiplication rules for Dirac bispinors with different masses have been found. Using the Lagrange formalism, the energy-momentum tensor and 4-current are received. It has been shown that the scalar product is a superposition of Klein-Gordon and Dirac scalar products.
