  1. 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
    鑒于已有大量文獻討論了核物質中的夸克凝聚,本文將討論在奇異物質中的夸克凝聚。而在介質中的夸克凝聚的基本公式可由hellmann - feynman理論導出,所以運用手征對稱自發破缺拉氏量以及平均場近似,我們就可以討論在奇異物質中的夸克凝聚,由所計算的結果表明: ( 1 )奇異物質中的夸克凝聚隨奇異物質密度的增大而單調減小。 ( 2 ) -凝聚的出現對衰減率有影響。
  2. 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
    大量實驗和理論研究表明,手征對稱自發破缺對于理解低能強相互作用十分重要,而夸克凝聚又是導致手征對稱自發破缺的因素。按goldstone理論,伴隨手征對稱自發破缺應該會有零質量的goldstonebosons產生。而對于這一條件的實現有線性和非線性兩種方法本文將用非線性的方法將手征對稱自發破缺應用于su ( 3 )模型即重子八重態,得出描述其強相互作用的手征對稱自發破缺lagrange密度。
