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

摘要

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