Description
The correlator of topological charge densities χ(Q2) in QCD is calculated in the domain of low Q2. Based on the Ward identities, the low energy theorems are proven. The value of the first derivative χ'(0) found recently by QCD sum rules is used. The contributions of pseudoscalar quasi-Goldstone bosons as intermediate states in the correlator are calculated with the account η-π mixing
