Study of the $$\boldsymbol{e^{+}e^{-}\rightarrow}{\pi}^{\boldsymbol{+}}{\pi}^{\boldsymbol{-}}{\pi}^{\mathbf{0}}$$ with the CMD-3 Detector at the VEPP-2000
We present preliminary results of the cross-section measurement of the $$e^{+}e^{-}\rightarrow\pi^{+}\pi^{-}\pi^{0}$$ process based on an integrated luminosity of about 51.4 pb $${}^{-1}$$ collected with the CMD-3 detector at the VEPP-2000 collider in the center-of-mass energy region below 1 GeV. A systematic uncertainty of the measurement is estimated as $$\sim 2.4\%$$ . The measured cross-section is analyzed in the framework of the vector meson dominance model taking into account an interference of the $$\rho,\omega,\phi,\omega^{\prime},\omega^{\prime\prime}$$ resonances. The preliminary parameters for the $$\omega$$ and $$\rho$$ resonances are obtained.
