First Look on the Process e+e− → π+π−π0 in the ω-Meson Energy Region with the CMD-3 Detector at the Electron-Positron Collider VEPP-2000

Abstract

The measurement of the cross-section of the process π+π−π0 with the CMD-3 detector at the electron-positron collider VEPP-2000 in the energy region below 1 GeV in c.m.s. based on a part of the collected statistics with an integrated luminosity of about 16.35 pb−1 is presented. The measured cross-section has been analyzed in the framework of the vector meson dominance model taking into account the interference of ρ, ω, φ, ω0, ω00 resonances.
