Abstract

The processes e+e−→K±K∗∓(892)e^{+}e^{-} \rightarrow K^{\pm} K^{*\mp}(892) and e+e−→ηϕ(1020)e^{+}e^{-} \rightarrow ηϕ(1020) are calculated in the framework of the extended Nambu-Jona-Lasinio model. The intermediate vector mesons ρ(770),ω(782),ϕ(1020)ρ(770), ω(782), ϕ(1020) and their first radially-excited states are taken into account. The obtained results are in satisfactory agreement with the experimental data. The predictions for the cross sections of the reactions e+e−→K±K∗∓(1410)e^{+}e^{-} \rightarrow K^{\pm} K^{*\mp}(1410), e+e−→η′(958)ϕ(1020)e^{+}e^{-} \rightarrow η^{'}(958) ϕ(1020) and e+e−→ηϕ(1680)e^{+}e^{-} \rightarrow ηϕ(1680) were made.
