Abstract

Adopting a Ũ₁₂ four-quark interaction as the potential input to the Bethe-Salpeter equation for the quark-antiquark system we can obtain nonets of bound 0^- and 1^- meson states. Owing to the presence of a spin-splitting term in the kernel, the masses and coupling constants of the composites deviate from the common values one uses in a phenomenological Ũ₁₂ field theory of quarks and mesons; the magnitudes of these changes are calculated in detail.
