Departures from Ũ12 in a relativistic quark model

J. Daboul, R. Delbourgo

Research output: Contribution to journalArticlepeer-review


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.
