Can the Isgur-Karl model be successfully applied to meson-baryon two-body reactions?

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

Via the additivity assumption, the model of baryon structure formulated by Isgur and Karl is applied to quasi-two-body meson-baryon scattering. The model offers no improvement over the strictSU (6) case, nor will other configuration-mixing models which do not alter the relative weight of the two diquark components of the nucleon. The features of the Isgur-Karl model are compared to those of a diquark model which has been successful in this area.

It is not difficult to prove that our predictions in the transversity frame are not affected by the Wigner rotations. We have therefore omitted them from (5)
