Abstract

The process e+eπ+πe^{+}e^{-} \to \pi^{+}\pi^{-} is described in the framework of the extended NJL model. Intermediate vector mesons ρ0(770)\rho^0(770), ω(782)\omega(782) and \rho'(1450)aretakenintoaccount.Ourresultsareinsatisfactoryagreementwithexperimentaldata.Thepredictionfortheprocess are taken into account. Our results are in satisfactory agreement with experimental data. The prediction for the process e^{+}e^{-} \to \pi\pi'(1300)isgiven.Herethemaincontributionisgivenbythediagramwithintermediate is given. Here the main contribution is given by the diagram with intermediate \rho'(1450)$ meson.
