A Model of the Extended Object as an Elementary Particle : Particles and Fields

概要

A model of the quantum extended object is presented, which stands for a particle with half-integer spin. In this theory, the spinor field ψ satisfies (□+m^2)ψ=0 only, when the interaction is ignored. With interaction, however, a ψ with <ψ>=φ(x) behaves like Dirac's particle with spin one half. The φ(x) expresses the inner structure of the particle. The degree of freedom for such an inner structure is the one alluded to for the first time by Schrodinger in connection to the intrinsic movement ``zitterbewegung''. There appear further ψ's with additional intrinsic angular momenta, that is ψ's with various half-integer spins. If the interaction allows such a series of states, the present theory predicts the presence of the rotational spectrum for the mass and the spin.
