8 Feb 2002 | | Journal: | PiN Newslett. 16 (2002) 9-18 | | Subject: | nucl-ex | | Abstract: | The regularities in the spectrum of the light baryon resonances are reviewed and compared with those of the light mesons. We discuss the occurrence of parity doublets and clusters, and note the trends in the values of the masses, widths, spins, and parities. The importance of SU(3) flavor is illustrated and the status of quark model calculations of the baryonic spectrum is reviewed. The absence of evidence for baryonic hybrids is particularly interesting. We propose to use better symbols for the baryon resonances which do not conflict with the simple quark structure of QCD. We shall comment also on fine tuning the Star System for the hadronic states. The importance of greater support for the construction and operation of secondary beams of $pi$, $K$, $ar p$, $vec{n}$ and $vecgamma$ up to 5 GeV/$c$ for the future of non-perturbative QCD is emphasized. | | Source: | arXiv, nucl-ex/0202005 | | Services: | Forum | Review | PDF | Favorites | |
