摘    要:夸克的真空凝聚是量子色动力学(QCD)研究中一个非常重要的问题.用完全穿衣服的夸克传播子研究了QCD真空性质和夸克的真空结构.计算了定域夸克的真空凝聚值,预言了夸克的真空结构.其结果与文献中的经验值相符合,也与Dyson-Schwinger方程解一致.说明参数化的夸克传播子是成功和可靠的.

关 键 词:夸克传播子    非定域QCD真空凝聚    定域QCD真空凝聚

Abstract:Study of quark vacuum condensate is one of the most important issues in the investigation of QCD.Based on the parameterized fully dressed quark propagator,the local quark vacuum condensate and the structure of non-local quark vacuum condensate are predicted.The results of our calculations are not only consistent with DSEs predictions but also in agreement with empirical values used widely in literature.The result shows that the parameterized form of quark propagator is an applicable and reliable approximation since its predictions are consistent with DSEs solutions and reproduce all physical quantities in an acceptable way.
Keywords:quark propagator  non-local QCD vacuum condensate  local QCD vacuum condensate
