Abstract
The process e+e−→π+π− is described in the framework of the extended NJL model. Intermediate vector mesons ρ0(770), ω(782) and \rho'(1450)aretakenintoaccount.Ourresultsareinsatisfactoryagreementwithexperimentaldata.Thepredictionfortheprocesse^{+}e^{-} \to \pi\pi'(1300)isgiven.Herethemaincontributionisgivenbythediagramwithintermediate\rho'(1450)$ meson.
