Model independent pion electromagnetic form factor behavior in the space-like region

Very precise data on σtot(e+e−→π+π−) recently measured by radiative return in Frascati and simultaneously the corrected Novosibirsk CMD-2 and SND data are transferred using the analyticity into the space-like region. As a result a rigorous pion electromagnetic form factor behavior is obtained, which is compared with AdS/QCD model predictions and existing data from electroproduction on proton.
