Quantum Field Theory of Extended Particles as a Model of Hadrons : Case of the Triple-Spinor Model

概要

Theory of quantized field of extended particles, especially in the case of the triple-spinor model, is developed in conformity with SU(6) and relativity. The former theoretical formalism of the infinite-component field theory derived from extended particle pictures is partially converted into the more realistic one. The internal dynamics of an extended hadronic system is represented by two different sets of wave equations ; one set with infinite-components determines the "supermultiplet structure" of hadrons, while the other set with finite components specifies the "space-time evolution of supermultiplets" of hadrons. The physically possible quantum states of the system are realized only in each individual coherent subspace of the inner Fock space, and all hadrons are unifiedly described as Fierz components of the U(6,6)-spinor (single-mass) local fields. A clear account is given of the relationship between these mechanism of the level structure, evolution and derivation of hadrons and the group-theoretical structure of our theory.
