- 論文の詳細を見る
We study all the SU(3) baryonic states known experimentally and identify them in the scheme of the deformed oscillator quark (DOQ) model. The DOQ model is motivated by confinement of quarks and chiral symmetry breaking, which are the most important nonperturbative phenomena of QCD. We find most of the baryonic states fall into the DOQ scheme. We then attempt to study the microscopic origin of the DOQ model using a model of three constituent quarks with two-body interactions. We find, however, that such a simple treatment is not able to produce the large deformation effect. We argue then that the confinement caused by the gluon dynamics is essentially important for the deformed baryons.
