Abstract
In this paper, we present the form factor \(\gamma {\text{*}}\omega {{\pi }^{0}}\) measurement in the virtual photon mass range 1 GeV < \(\sqrt {{{q}^{2}}} \) < 2 GeV in the \({{e}^{ + }}{{e}^{ - }} \to \omega {{\pi }^{0}} \to {{\pi }^{ + }}{{\pi }^{ - }}{{\pi }^{0}}{{\pi }^{0}}\) process. Measurements are based on the data acquired by the SND detector at the VEPP-2000 \({{e}^{ + }}{{e}^{ - }}\) collider in Novosibirsk. The obtained form factor is approximated in the vector meson dominance (VMD) model. The joint fitting of the form factor obtained in the SND and NA60 experiments is also performed.
