Abstract

Using the parameterized quark propagator proposed by us in our previous publication， the quark vacuum condensates and tensor susceptibility of QCD vacuum have been calculated. The results show that the tensor susceptibility strongly depends on the flavors of quark, but not on the variation of quark vacuum condensate. The quark vacuum condensate， however， is very sensitive to the change of cut off value of integration up limit， that is， it depends on the point of perturbative and nonperturbative QCD separation. Within the cut off region of 1 to 2 GeV2 used commonly， our calculated values of quark vacuum condensates are consistent with the empirical values and the predictions of other theoretical models. The prediction of the tensor susceptibility of this work is also consistent with other’s results.
