Abstract
The field theory of neutral vector particles interacting with conserved currents is investigated as an example of particle mixing. It is shown that a generalization of conventional renormalization is necessary when mixing occurs, and that the observable masses and coupling constants are sufficient to determine transition amplitudes, without recourse to mixing parameters. The universality of electric charge renormalization is not changed when photon-vector-meson mixing is possible.
