U(3)群与SU(3)规范不变性

U(3) Group with the SU(3) Gauge Invariance

给出U(3)群与SU(3)群的定义及关系,强子按味SU(3)群的不可约表示(多重态)分类,准确地预言了一些新的粒子,说明了强子的自旋、宇称、电荷、奇异数及质量等一系列性质的规律性.强子遵从相应的费米和波色统计,每一种夸克含有内部空间自由度,不同色夸克之间的强相互作用是通过传递带色的胶子而发生.而这一物理过程也需要用SU(3)群来描写.揭示了SU(3)对称性在强子结构研究中的重要性,关于SU(3)对称性的分析,对未知规律的探索有一定的参考价值.

The authors give the definition and relationship of U（3） and SU（3） group and the irreducible representation of SU（3） group（multiple） classification of hadron according to tastes,predict the new particles accurately and illustrate the hadron spin,parity,charge,and weird number,and also quality and a series of properties of regularity. Hadron follows corresponding Fermi and wave statistics of color,with each kind of quarks containing internal space degree of freedom and the strong interaction between different color quarks is passing to bring color of gluons. The physical process also needs to use the SU（3） to describe. This article reveals the SU（3） symmetry in the hadron structure and the importance of the research on the SU（3） the analysis of the symmetry. The exploration to the unknown laws has certain reference value.
