\eta(1475) and f_1(1420) resonances in \gamma\gamma* collisions and J/\psi\to\gamma(\rho\rho, \gamma\rho^0, \gamma\phi) decays

The available data on the $Q^2$ dependence of the $\gamma\gamma*(Q^2)\to K\bar K\pi$ reaction cross section in the energy region 1.35-1.55 GeV is explained by the $\eta (1475)$ resonance production in contrast to their conventional interpretation with the use of the $f_1(1420)$ resonance. It resolves theoretically the contradiction between the suppression of the $\eta (1475)\to \gamma \gamma$ decay width and the strong couplings of the $\eta (1475)$ to the $\rho \rho$, $\omega \omega$, and $\gamma {\rho }^0$ channels. The experimental check of our explanation requires definition of the spin-parity of the resonance contributions, $R$, in $\gamma\gamma*(Q^2)\to R\to K\bar K\pi$andin$J/\psi\to\gammaR\to\gamma\gamma(\rho^0, \phi)$. This will help to solve difficulties accumulated in understanding properties of the $\eta (1475)$ state and its nearest partners.
