Measurement of $\omega$ meson parameters in $\pi^{+}\pi^{-}\pi^{0}$ decay mode with CMD-2
About 11 200 $ e^+e^- \to \omega \to \pi^+\pi^-\pi^0$ events selected in the center of mass energy range from 760 to 810 MeV were used for the measurement of the $\omega$ meson parameters. The following results have been obtained: $\sigma _{0}=(1457 \pm 23 \pm 19 )$ nb, $m_{\omega }=(782.71 \pm 0.07...
