英文摘要Based on the quark propagator in the instanton dilute liquid approximation, we have determined the quark condensate ((q) over bar q), the mixed quark gluon condensate g(s)((q) over bar G(mu nu)sigma(mu nu)q) and the four-quark condensate ((q) over bar Gamma q (q) over bar Gamma q) at the mean-field level in the framework of global color symmetry model. The numerical calculation shows that our result is compatible with the range obtained within other nonperturbative approaches. In particular, we have found that even at the mean-field level the naive vacuum saturation approximation is not a good approximation when we consider nonlocal four-quark condensate.
