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

Abstract

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.
