Description

The e+e- → ωπ0 process near the φ resonance was studied in the experiment on the VEPP-2M e+e- collider with a spherical neutral detector. The both basic modes of the ω meson decay: ω → π+π-π0 and ω → π0γ were studied. The probability of the φ → ωπ0 decay was measured by the interference wave value in the cross section of the e+e- → ωπ0 → π+ π-π0 π0 reaction. The ratio of the ω meson decay widths: Γ(ω → π0γ)/Γ(ω → π+π-π0) is obtained from the ratio of the cross sections in the two modes

Abstract (Russian)

В эксперименте на e+e--коллайдере ВЭПП-2М со сферическим нейтральным детектором изучалась реакция e+e- → ωπ0 в области φ-резонанса. Исследовались обе основные моды распада ω-мезона: ω → π+π-π0 и ω → π0γ. По величине интерференционной волны в сечении реакции e+e- → ωπ0 → π+ π-π0 π0 измерена вероятность распада ω → ωπ0. Из соотношения сечений в двух модах получено отношение ширин распада ω-мезона: Γ(ω → π0γ)/Γ(ω → π+π-π0)
