Abstract
QCD Sum Rules are used to study nonperturbative behaviour of quark pro pagators. Instead of using operator product expansion, we use Dyson-Sc hwinger equations and Ward-Takahashi identity. We found that good agre ement with the data is obtained for logarithmically divergent effectiv e quark mass.
