Abstract
We determine the magnetic dipole moment of the rho meson using preliminary data from the BaBar Collaboration for the [Formula: see text] process, in the center of mass energy range from 0.9 to 2.2 GeV. We describe the [Formula: see text] vertex using a vector meson dominance model, including the intermediate resonance contributions relevant at these energies. We find that [Formula: see text] in [Formula: see text] units.
