RELATIVISTIC WAVE-EQUATION FOR HYPOTHETICAL COMPOSITE QUARKS

A two-body wave equation is derived, corresponding to the hypothesis ( discussed already in the past) that u and d current quarks are relativ istic bound states of a spin-1/2 preen existing in two weak flavors an d three colors, and a spin-0 preen with no weak flavor nor color, held together by a new strong but Abelian, vectorlike gauge force. Some no nconventional (though somewhat nostalgic) consequences of this strong Abelian binding within composite quarks are pointed out. Among: them a re: new tiny magnetic-type moments of quarks (and nucleons) and new is omeric nucleon states possibly excitable at some high energies. The la tter may arise through a rearrangement mechanism for quark preens insi de nucleons. in the interaction q (q) over bar --> q (q) over bar of p reen-composite quarks, beside the color forces, there act additional e xchange forces corresponding to diagrams analogical to the so called d ual diagrams for the interaction pi pi --> pi pi Of quark-composite pi ons.
