轻重重子质量:1/N_c展开和夸克模型

Light and heavy baryon masses: the 1/N_c expansion and the quark model

F. Buisseret, C. Semay, Fl. Stancu, N. Matagne

摘要:

本文建立了夸克模型与描述重子共振态的1/N_c展开质量公式之间的联系。结果表明,这两种方法在轻、重子区存在显著的相容性。特别地,用夸克模型解释了1/N_c展开式中用于重子分类的带数,两种方法的质量公式是一致的。

英文摘要:

We establish a connection between the quark model and the 1/N_c expansion mass formulas used in the description of baryon resonances. We show that a remarkable compatibility exists between the two methods in the light and heavy baryon sectors. In particular, the band number used to classify baryons in the 1/N_c expansion is explained by the quark model and the mass formulas for both approaches are consistent.
