Abstract

Parameterization of the form factors of f1(1285) meson is proposed. This parameterization is consistent with the available experimental data on the cross sections of f1(1285) meson production in the processes e+e→f1(1285) and e+e→e+ef1(1285), as well as on the widths of the decays f1(1285)→e+e, f1(1285)→ρ0γ, f1(1285)→ρ0π+π, and f1(1285)→2π+. Our parameterization is also consistent with the predictions for the asymptotic behavior of these form factors.
