Study of the process e⁺e^-→π⁺π^-π⁰ with the CMD-3 detector at the electron-positron collider VEPP-2000

The cross section of the process e⁺e^-→π⁺π^-π⁰ was measured with the CMD-3 detector at the electron-positron collider VEPP-2000 in the energy region from 750 MeV to 800 MeV in c.m.s. This measurement was based on the data collected in 2013 and related to an integrated luminosity of about 7.8 pb^-1. The procedure for obtaining the Born cross section and determining the parameters of the ω-meson was worked out. The preliminary ω-meson parameters mω = 782.70 ± 0.02 ± 0.11 MeV, Γω = 8.74 ± 0.05 ± 0.22 MeV, σ⁰(ω → π⁺π^-π) = 1545 ± 4 ± 39 nb were obtained. The results were compared with previous data and proven to demonstrate a good agreement with them. (authors)
