Yukawa interactions among hadrons are examined from a unified viewpoint in the ur-citon scheme (which is a relativistic generalization of the quark model), where all hadrons are described as Fierz-components of multi-local fields. A remarkable point of our scheme is that respective interactions among all hadrons are unifiedly determined through “ur-citon interactions”, of which two typical forms are examined here.
As for the strong vertices among ground hadrons our universality is shown to be valid for both cases. Moreover, by applying it to photon processes using the vector-meson dominance model, it is seen that a \tildeU(12)-symmetrical interaction (of which ur-citon interactions are due merely to the “connector”) predicts a slightly large rate for radiative meson decays, while a “rest-symmetrical” interaction is quite satisfactory.
