Abstract
Starting from effective Lagrangians which combine a gauge formulation of vector meson dominance with chiral Lagrangians, the coupling of the φ to the nucleon, which is zero at tree level due to the OZI rule, is calculated perturbatively considering loop contributions to the electric and magnetic form factors. We obtain reasonably smaller values for both form factors than those for ρNN and consistent with the expected order of magnitude of the OZI rule violation. The role of the φ– ω mixing is also investigated.
