The processes e+e−→K±(K∗∓(892),K∗∓(1410))e+e−→K±(K∗∓(892),K∗∓(1410)) and e+e−→(η,η′(958))(ϕ(1020),ϕ(1680)) in the extended Nambu–Jona-Lasinio model
Abstract
The processes e+e−→K±K∗∓(892) and e+e−→ηϕ(1020) are calculated in the framework of the extended Nambu–Jona-Lasinio model. The intermediate vector mesons 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−→η′(958)ϕ(1020) and e+e−→ηϕ(1680) were made.
