摘要: 对多夸克态特别是双重子态的半个世纪的研究进展进行了概述。利用动力学对称性，推导了能够合理地描述多夸克态质量的Gursey-Radicati 公式，然后在MIT 袋模型和可以很好描述重子-重子相互作用的夸克蜕定域色屏蔽模型中讨论了各种可能的双重子。


The progress in the study of multi-quark states for the last half century is reviewed schematically and the dibaryon sector is emphasized. By employing the dynamical symmetry, the Gursey-Radicati mass formula, which can give a reasonable description of the masses of multi-quark states, can be reproduced. The dibaryons in bag model and realistic quark model, quark delocalization color screening model, are discussed.
