摘要：

Coefficient functions of the operator G2 in the large mass expansions of correlators of two (pseudo) scalar and (pseudo) vector currents are calculated in the two-loop approximation. The obtained results are numerically sizeable and could be important for the phenomenological determination of the value of the corresponding condensate <G2>.
