$$\left\langle {:\bar \psi \psi :} \right\rangle $$ and three-point functions in QCD.

We calculate the coefficients of $$\left\langle {:\bar \psi \psi :} \right\rangle $$ to leading order in α in the operator product expansion of the fundamental three-point functions of QCD in the deep Euclidean region. We demonstrate that these coefficients satisfy the Ward identities. [ABSTRACT FROM AUTHOR]
