Abstract | Based on the quark propagator derived in the instanton dilute liquid approximation, the quark condensate <(q) over barq >, the mixed quark gluon condensate g(a)< qG(muv)sigma (muv)q > the four-quark condensate <(q) over bar Gammaq (q) over bar Gammaq > and tensor, pion vacuum susceptibilities have been calculated at the mean-field level in a nonperturbative QCD model. The numerical results are compatible with the values obtained within other nonperturbative approaches. The calculated masses and decay constants of pi and sigma mesons are close to the experimental values. These results show that the instanton medium might be a good approximation of the QCD vacuum. |
