On Superluminal Velocities
Keywords: superluminal velocities, free particles, zero initial mass, small-distance derivative
In the present work we investigate the Dirac equation in two dimensions for free particles and we obtain sumluminal and superluminal velocities. Studying also the above equation with zero initial mass, for Caldirola-Montaldi (C.M.) and small-distance derivative (S.D.D.) model, we prove the existence of superluminal velocities.
