Baryon Resonances in Constituent-Quark Models

  • W. Plessas
Part of the Few Body Systems book series (FEWBODY, volume 13)


We discuss the description of baryon resonances within constituentquark models by looking at spectroscopy and mesonic decays. In particular, we adress the set-up, the kind of dynamics, and the calculational framework for constituent quark models. Results are presented for the case of the constituent-quark model relying on the novel Goldstone-boson-exchange mechanism for the quark-quark hyperfine interaction. We locate the reasons for obvious shortcomings in the description of mesonic decays and hint to improvements that might be essential to reach a better understanding of low-energy hadron reactions within constituent-quark models.
