The process $e^+e^-\toπ^+π^-π^0$ in the energy range 2E_0=1.04

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/178756In the experiment with the SND detector at VEPP-2M e^+e^- collider the process $e^+e^-\toπ^+π^-π^0$ was studied in the energy range 2E_0 from 1.04 to 1.38 GeV. A broad peak was observed with the visible mass $M_{vis}=1220\pm 20$ MeV and cross section in the maximum $σ_0\simeq 4$ nb. The peak can be interpreted as a $ω$-like resonance $ω(1200)$.10 pages LATEX and 5 figuresHigh Energy Physics - ExperimentThe process $e^+e^-\toπ^+π^-π^0$ in the energy range 2E_0=1.04 - 1.38 GeVtext
