Rigorous pion electromagnetic form factor behavior in the space-like region

Abstract

New precise experimental information on ${\sigma }_{tot}(e^{+}{e}^{-}\to {\pi }^{+}{\pi }^{-})$ is transferred into the space-like region, by taking advantage of the analyticity. As a result a rigorous pion electromagnetic form factor behavior is obtained. The latter with some existing model predictions is compared.
