    "abstract": "We present a procedure to derive a covariant electromagnetic current operator\nfor a system made up by two scalars constituents. Using different wave\nfunctions we fitted their parameters to the experimental data of the pion form\nfactor, obtainig great discrepancy at low momentum transfer. Introducing the\nVector Meson Dominance corrective factor, we obtained a better fit to the data.",
