Experimental study of the e+e- → π+π-π0 reaction by SND detector in the energy range [formula].

The review of the SND results of the e+e¯ → π+π¯π0 process study in the energy range _s _ √s = 42 − 1.38 GeV at VEPP-2M collider, based on about 2×106 selected events, is presented. The total cross section, parameters of the ρ, ω, φ resonances, and ω′, ω″ states were obtained. It was found that ?p and ωπ0 intermediate states describe the reaction dynamics. The experimental data cannot be described by a sum of only ω, φ, ω′ and ω″ resonances contributions. This can be interpreted as a manifestation of the ρ → 3π decay, suppressed by G-parity, with relative probability B(ρ → 3π) =(1.01±0.360.54) × 10-4. [ABSTRACT FROM AUTHOR]
