η(1475) and f1(1420) resonances in J/ψ→γ(ρρ,γρ0,γϕ) decays and γγ⁎ collisions

We resolve the contradiction between the suppression of the η(1475)→γγ decay and the strong couplings of the η(1475) to the ρρ,ωω, and γρ0 channels by taking into account the effect of the heavy vector mesons ρ′0,ω′,ϕ′. This lead us to the explanation of the resonancelike Q2 dependence on the reaction cross section by η(1475) production, which is an alternative to the conventional explanation of dependence by f1(1420) production. The experimental check of our scenario requires definition of the spin-parity of the resonance contributions, R, in and in J/ψ→γR→γγ(ρ0,ϕ). This will help to solve difficulties accumulated in understanding properties of the η(1475) state and its nearest partners.
