On the predictions of dip-effect in Q^2 dependence of electromagnetic and electroweak formfactors of pi-meson decay and their experimental verification

In present note the arguments in favour of future high statistical measurements of the formfactors that describe pi-meson decays into lepton-antilepton pair and photon are presented. It is shown that these formfactors Q^2 dependence contains the important information on the dynamics of quark motion inside a hadron.
