| 摘 要： | 研究了夸克约束的重子受激态和手征对称破缺。首先讨论了空间变形的重子激发。作为形变的信息，讨论质量和电磁跃迁。这样的空间结构的讨论给出关于夸克结合机制和夸克约束的信息。然后考虑了重子的手征对称性，并研究正负宇称的重子。可以表明存在重子的2种手征对称性的不同表示。按照线性σ模型的项研究它们唯象的结果。

| Abstract: | It is studied Baryon excited states for quark confinement and chiral symmetry breaking.Spatially deformed baryon excitations are firstly discussed. As marks of deformation, masses and electromagnetic transitions are investigated in detail. Such a study of spatial structure is expected to provide information on quark binding mechanism and hence quark confinement. In terms of a deformed oscillator quark model the jeformed baryons was studied. Then consided the chiral symmetry for laryons and studied positive and negative parity baryons, N and N * . It can be displayed there are two distinctive repre-sentations of chiral symmetry for baryons. Investigated masses,pion-NN * couplings and charges of N and N * using linear sigma model. |
