Abstract:

A model is proposed in which most of baryon resonances are understood as octet and decuplet composite systems of the 1/2+ octet baryon and the 0- octet meson. A classification of baryons based on the model is proposed in the form of periodic table. Experimental results and phenomenological rules to suggest such a cluster structure of baryons are explained. The mass formula of the model is capable of explaining most of observed baryon resonances. Interactions between the constituent baryon and meson are shown almost independent of their isospin, hypercharge and relative angular momentum. The spin-orbit coupling part of the interactions is found to be consistent with the sign of polarization of recoil protons in π-N scattering.
