ymmetry model is derived. Within this approach it is shown that the vacuum condensates are free of ultraviolet divergence which is different from previous studies As special cases, the two-quark condensate <qq-> and the mixed quark-gluon condensate g<q-Gμνσμνq> are calculated. A comparison with the results of other nonperturbative QCD approaches is given.

摘要

The relation between the axial vector current of current quark and that of constituent quark has been studied within the framework of the global color symmetry model. Gluon dressing of the axial vector vertex and the quark self-energy function are described by the inhomogeneous Bethe-Salpeter equation in the ladder approximation and the Schwinger-Dyson equation in the rainbow approximation, respectively.
