摘要：

In the extended Nambu-Jona-Lasinio (NJL) model the total cross sections of the processes e(+)e(-) -> [eta, eta', eta(1295), eta(1405)]gamma at energies up to 2 GeV are calculated. The intermediate vector mesons rho(770), omega(782), phi(1020), rho'(1450), omega'(1420), and phi'(1680) are taken into account. The latter three mesons are treated as the first radial excited states. They are incorporated into the NJL model by means of polynomial form factors. The calculation results are in satisfactory agreement with the experimental data obtained with the SND detector at VEPP-2M, Novosibirsk. The predictions given for the process e(+)e(-) -> [eta', eta(1295), eta(1405)]gamma have not been experimentally tested yet. DOI: 10.1103/PhysRevC.87.045203
