| Abstract: | The mixed quark-gluon condensate from the global color symmetry model isderived. It is shown that the mixed quark-gluon condensate dependsexplicitly on the gluon propagator.This interesting feature may be regarded as an additional constraint on the model of gluon propagator. The values of the mixed quark-gluon condensate from some ansatz for thegluon propagator are compared with those determined from QCD sum rules. |
