- W2052018940 abstract "Starting from a model of relativistic composite system in the single-electron-theoretical treatment presented by Glockle, Nogami and Fukui, we intend to present a composite system in motion in the positron-theoretical treatment. Our study is made by using a manifestly covariant way of the Bethe-Salpeter equation, taking the Fermi-type interaction. Although a divergence appears in the eigenvalue equation, it is found to be dealt with in an invariant manner. In other words, it is taken away by reinterpreting the coupling constant, that is, a kind of renormalization of the coupling constant. We obtain a particle-particle bound-state solution in one of the two cases of the effective coupling constant of the vector-type interaction and a particle-anti-particle bound-state solution in the other case" @default.
