Effective-Lagrangian formulation of generalized vector dominance

The Lagrangian of Lee and Zumino is generalized to include several vector mesons. Their mutual interactions are chosen so as to guarantee a current-vector-fields proportionality relation analogous to the original current-field proportionality relation of Kroll, Lee, and Zumino. Implications of the new Lagrangian for the electromagnetic couplings of charged vector mesons are studied. It is shown, in particular, that the ρ±(770) can carry any magnetic moment in this scheme.
