It is shown that these formfactors Q^2 dependence contains the important information on the dynamics of quark motion inside a hadron.10 pagesHigh Energy Physics - PhenomenologyOn the predictions of dip-effect in Q^2 dependence of electromagnetic and electroweak formfactors of pi-meson decay and their experimental verificationtext
