Elementary particles of conventional field theory as Regge poles. III

It is shown that an elementary particle of conventional field theory may, under certain conditions, lie on a Regge trajectory. These conditions are that the system contain a "nonsense" channel at the angular momentum of the particle and that the Born approximation scattering amplitude factor in a well-defined way. They are satisfied by a spin 1/2 fermion interacting through a conserved current with a spin one neutral boson. The particle in question is the fermion. © 1964 The American Physical Society
