Abstract: The non-local vacuum condensates of QCD describe the distributions of quarksand gluons in the non-perturbative QCD vacuum. Physically, this means thatvacuum quarks and gluons have nonzero mean-squared momentum, called virtuality.In this paper we study the quark virtuality which is given by the ratio of thelocal quark-gluon mixed vacuum condensate to the quark local vacuum condensate.The two vacuum condensates are obtained by solving Dyson-Schwinger Equations ofa fully dressed quark propagator with an effective gluon propagator. Using ourcalculated condensates, we obtain the virtuality of quarks in the QCD vacuumstate. Our numerical predictions differ from the other theoretical modelcalculations such as QCD sum rules, Lattice QCD and instanton models.
