baryon octet meaning in Chinese
重子八重态
Examples
- In this paper , we take a way which realizes this constraint by a nonlinear method and generalize the chiral effictive model to su ( 3 ) including the baryon octet . by this means , we obtain the chiral symmetry spontaneous breaking lagrange density which depicts the strong interactions
本文采用对这一条件进行非线性实现的方法将手征自发破缺的等效模型推广到su ( 3 )模型，即重子八重态，得出描写强相互作用的手征自发破缺的lagrange密度。 - There has been many papers to discuss the in - medium quark and gluon condensates in nuclear matter which use the models with su ( 2 ) l su ( 2 ) r sym - metry . now , we make use of the chiral model su ( 3 ) l su ( 3 ) n including the baryon octet to discuss the quark condensate < qq > in strange matter , where q is an up or down quark field . on the one hand , from the experimetal data , it is found that < qq > vac = - ( 225 25mev ) 3 , on the other hand , with the hellmann - feynman theorem , quark condensate can be evaluated on the hadronic level . in this paper , we will investigate the quark condensate in strange matter with the chiral symmetry su ( 3 ) l x su ( 3 ) rspontaneous breaking lagrangian to obtain the variation of the quark condensate in the strange matter when the baryon number change . it can be applied to understand the neutron stars when the neutron star are considered to be constructed by the strange matter . because nertron stars are homogeneous and at very low temperature , we will use the mean - field approximation and zero temperature throughout this paper
鉴于已有大量文献讨论了核物质中的夸克凝聚，本文将讨论在奇异物质中的夸克凝聚。而在介质中的夸克凝聚的基本公式可由hellmann - feynman理论导出，所以运用手征对称自发破缺拉氏量以及平均场近似，我们就可以讨论在奇异物质中的夸克凝聚，由所计算的结果表明： ( 1 )奇异物质中的夸克凝聚随奇异物质密度的增大而单调减小。 ( 2 ) -凝聚的出现对衰减率有影响。
