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-Radicatimass 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.
