Abstract

We determine the magnetic dipole moment of the rho meson using preliminary data from the BaBar Collaboration for the e⁺e^- → π⁺π^-2π⁰ process, in the center of mass energy range from 0.9 to 2.2 GeV. We describe the γ* → 4π vertex using a vector meson dominance model, including all intermediate resonance contributions. We find that μ_ρ = 2.1 ± 0.5 [e/2m_ρ].
