Abstract:
The Taylor expansions of the quark and mixed condensates are presented Lorents gauge,which as well as the expansion of gluon condensate can be used to calculate the Wilson coefficients of the nonperturbative correction terms in the operator product expansion. In contrast to those current expansions in the sum rules in the fixed gauge,the new expansion has the advantage of being translational invariant.
