    "abstract": "We calculate the electromagnetic form factors of the nucleon up to fourth\norder in manifestly Lorentz-invariant chiral perturbation theory with vector\nmesons as explicit degrees of freedom. A systematic power counting for the\nrenormalized diagrams is implemented using both the extended on-mass-shell\nrenormalization scheme and the reformulated version of infrared regularization.\nWe analyze the electric and magnetic Sachs form factors, $G_E$ and $G_M$, and\ncompare our results with the existing data. The inclusion of vector mesons\nresults in a considerably improved description of the form factors. We observe\nthat the most dominant contributions come from tree-level diagrams, while loop\ncorrections with internal vector meson lines are small.",
