Quark-Model Identification of Baryon Ground and Resonant States

Understand

We present a new classification scheme of baryon ground states and resonances into SU(3) flavor multiplets.

• The scheme is worked out along a covariant formalism with relativistic constituent quark models and it relies on detailed investigations of the baryon spectra, the spin-flavor structure of the baryon eigenstates, the behaviour of their probability density distributions as well as covariant predictions for mesonic decay widths.
• The results are found to be quite independent of the specific types of relativistic constituent quark models employed.
• It turns out that a consistent classification requires to include also resonances that are presently reported from experiment with only two-star status.
