Complex space-time and the classification of elementary particles
Lu Lin
It is shown that the Dirac theory implies complex space-time and complex space-time can lead to the Dirac equation. It is suggested that fermions are grouped into doublets, those d…

On the passibility of a short-lived free Dirac particle
Lu Lin
A time-decaying Dirac equation is suggested. For a free particle with rest mass about 0.5GeV, the live-time is about 10**(-25) second in the rest frame.

The velocity and angular momentum of a free Dirac electron
Lu Lin
It is shown that, in Dirac theory, there is a spatial velocity of a free electron which commutes with the Hamiltonian, so it is a conserved quantity of the motion. Furthermore, the…

On the possibility of a complex 4-dimensional space-time manifold
Lu Lin
The possibility of a complex 4-dimensional space-time manifold is suggested. This may imply the existence of a matter wave.
