Abstract

Parameterization of the form factors of f1(1285)f_1 (1285) meson is proposed. This parameterization is consistent with the available experimental data on the cross sections of f1(1285)f_1 (1285) meson production in the processes e+ef1(1285)e^+e^- \to f_1 (1285) and e+ee+ef1(1285)e^+e^- \to e^+e^-f_1 (1285), as well as on the widths of the decays f1(1285)e+ef_1 (1285)\to e^+e^-, f1(1285)ρ0γf_1 (1285)\to \rho^0\gamma, f1(1285)ρ0π+πf_1 (1285)\to \rho^0\pi^+\pi^-, and f1(1285)2π+2πf_1 (1285)\to 2\pi^+2\pi^-. Our parameterization is also consistent with the predictions for the asymptotic behavior of these form factors.
