摘要
We resolve the contradiction between the suppression of the eta(1475) -> gamma gamma decay and the strong couplings of the eta(1475) to the rho rho, omega omega, and gamma rho(0) channels by taking into account the effect of the heavy vector mesons rho'(0), omega', phi'. This lead us to the explanation of the resonancelike Q(2) dependence on the gamma gamma*(Q(2)) -> K (K) over bar pi reaction cross section by eta(1475) production, which is an alternative to the conventional explanation of dependence by f(1)(1420) production. The experimental check of our scenario requires definition of the spin-parity of the resonance contributions, R, in gamma gamma*(Q(2)) -> R -> K (K) over bar pi and in J/psi -> gamma R -> gamma gamma(rho(0), phi). This will help to solve difficulties accumulated in understanding properties of the eta(1475) state and its nearest partners.
