Abstract

Using experimental data on the imaginary part of the pion form factor obtained from the reaction e+eπ+π up to the inelastic threshold tπ0ω and a simple parametrization for it (respecting QCD constraints) at the range of momenta tπ0ωe+eπ+π data is carried out. The analysis reveals no global incompatibility of the spacelike electroproduction data with the timelike data, claimed by other authors recently.
