The processes $e^{+}{e}^{-}\to K^{\pm }(K^{\ast \mp }(892),K^{\ast \mp }(1410))$ and $e^{+}{e}^{-}\to (\eta ,{\eta }^{{}^{\prime }}(958))(\varphi (1020),\varphi (1680))$ in the extended Nambu-Jona-Lasinio model

Abstract

The processes $e^{+}{e}^{-}\to K^{\pm }{K}^{\ast \mp }(892)$ and $e^{+}{e}^{-}\to \eta \varphi (1020)$ are calculated in the framework of the extended Nambu-Jona-Lasinio model. The intermediate vector mesons $\rho (770),\omega (782),\varphi (1020)$ 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 $e^{+}{e}^{-}\to K^{\pm }{K}^{\ast \mp }(1410)$, $e^{+}{e}^{-}\to {\eta }^{{}^{\prime }}(958)\varphi (1020)$ and $e^{+}{e}^{-}\to \eta \varphi (1680)$ were made.
