Fermion mass, a new interpretation and approach to fermionic vacuum and associated quantum field theories

Abstract

We argue that all fermionic states characterized by the (four) velocity not momentum of the fermion are always occupied by a single fermion. So there is no fermion number violation whatsoever. The mass of an elementary particle is not determined by field equations and is quite arbitrary. Though constant in the free state, interaction may cause a fermion to go from finite to zeromass state, interpreted as vacuum, and vice versa. We argue that a massless fermion can't be detected. Since occupation number is not fixed the arguments leading to the above conclusions cannot be extended to bosons. We calculate scattering amplitude for a typical process like Rutherford scattering in the light of the present discussion to show that there is no contradiction with the experimental results.
