Abstract
The process e⁺e⁻ → π⁺π⁻πγ is studied at a center-of-mass energy near the Υ(4S) resonance using a data sample of 469 fb⁻¹ collected with the BABAR detector at the PEP-II collider. We have performed a precise measurement of the e⁺e⁻ → π⁺π⁻π⁰ cross section in the center-of-mass energy range from 0.62 to 3.5 GeV. In the energy regions of the ω and ϕ resonances, the cross section is measured with a systematic uncertainty of 1.3%. The leading-order hadronic contribution to the muon magnetic anomaly calculated using the measured e⁺e⁻ → π⁺π⁻π⁰ cross section from threshold to 2.0 GeV is (45.86±0.14±0.58) × 10⁻¹⁰. From the fit to the measured 3π mass spectrum we have determined the resonance parameters Γ(ω → e⁺e⁻)B(ω → π⁺π⁻π⁰) = (0.5698±0.0031±0.0082) keV, Γ(ϕ → e⁺e⁻)B(ϕ → π⁺π⁻π⁰) = (0.1841±0.0021±0.0080) keV, and B(ρ → 3π) = (0.88±0.23±0.30) × 10⁻⁴. The significance of the ρ → 3π signal is greater than 6σ. For the J/ψ resonance we have measured the product Γ(J/ψ → e⁺e⁻)B(J/ψ → 3π) = (0.1248±0.0019±0.0026) keV.
