  • 手赵称性

例句与用法

  • Influence of chiral symmetry spontaneous breaking on neutron star
    手征对称性自发破缺对中子星的影响
  • Chiral symmetry spontaneous breaking and confinement are two very important properties of low energy qcd
    手征自发破缺和色禁闭是低能qcd的两个重要性质。
  • According to goldstone theorem , the goldstone bosons with zero mass will emerge as the chiral symmetry is spontaneously broken
    由goldstone理论可知，当手征自发破缺时会生成零质量的goldstone玻色子。
  • The result is consistent with the usual assumption that the chiral symmetry is gradually restored as density of a nuclear matter increases
    这个结果和手征对称性随着核物质密度增加而逐渐恢复这一通常假设是符合的。
  • 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。
  • The results show that the chiral symmetry is restored partially when the strange matter density increases and 2 plays a very important role in the strange matter which may approach the constituents of the neutron stars . in additions , we can find that the strange matter density where the - condensate emerges is led to the ratio of the nucleon number to baryon number . and the occurrence of - condensate is only in certain density and gradually increases for higher density , so we guess that - field may be necessary to carefully consider for studying the neutron stars
    ( 3 ) -凝聚出现时所对应的奇异物质密度值与核子在奇异物质中的比例有关。另外，虽然本文对夸克凝聚的讨论是在低密度的奇异物质中进行的，但是-凝聚的出现却需达到一定的密度值并且随密度的增大而递增，所以我们推测场可能对于仔细研究中子星是一必要因素。
  • 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。
  • In quantum chromodynamics ( qcd ) , vacuum is not trivial , that is , vacuum carry quantum numbers . such a behavior is embodied by non - perturbative con - densates of quarks and gluons . since hadrons are excitations with respect to the vacuum , hadronic properties are ultimately related to properties of the vacuum . based on the vacuum structure , some hadron properties have been described well . in the low energy region , qcd has two very important proper - ties : chiral symmetry spontaneous breaking and confinement , which are closely related to the vacuum characteristics of qcd . much experiments and theoretical studies have shown that chiral symmetry spontaneous breaking is very important to understand the low - energy feature of the strongly interacting physics , and the quark condensates give an expression to chiral symmetry spontaneous breaking . according to goldstone ' s theorem , the goldstone bosons with zero mass will emerge as the chiral symmetry is spontaneously broken . there are two ways : inear and non - linear methods to carry out this constraint . in our paper , we will use the non - linear method
    大量实验和理论研究表明，手征对称自发破缺对于理解低能强相互作用十分重要，而夸克凝聚又是导致手征对称自发破缺的因素。按goldstone理论，伴随手征对称自发破缺应该会有零质量的goldstonebosons产生。而对于这一条件的实现有线性和非线性两种方法本文将用非线性的方法将手征对称自发破缺应用于su ( 3 )模型即重子八重态，得出描述其强相互作用的手征对称自发破缺lagrange密度。
