Consistent analysis of $f_1 (1285)$ meson form factors

Understand

Parameterization of the form factors of $f_1 (1285)$ meson is proposed.

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