Abstract

Correlation functions of vector and axial currents (with flavor content ud and us) are calculated in the "instanton liquid" model. Results are compared with the data on e⁺e^-→ hadrons (I = 1) and τ→ν_τ+hadrons, respectively. Very good agreement is found, especially in the vector case, in which the theory does reproduce a "fine tuning" of ρ{variant}(770), ρ{variant}(1450), ρ{variant}(1700) and the non-resonance contributions existing in data.
