Vacuum condensates of QCD

【摘要】 <正>We study the properties of QCD vacuum state in this paper.The values of various local quark vacuum condensates,quark-gluon mixed vacuum condensates,and the structure of non-local quark vacuum condensate are predicted by the solution of Dyson-Schwinger Equations in"rainbow"approximation with three sets of different parameters for effective gluon propagator.The light quark virtuality is also obtained in a consistent way.Our all theoretical results here are in good agreement with the empirical values used widely in literature and many other theoretical calculations.更多还原
