    "abstract": "We perform a global analysis of the experimental data of the electromagnetic\nnucleon form factors, in space-like and time-like regions. We give the\nexpressions of the observables in annihilation processes, such as $p+\\bar{p}\\to\n\\ell^+ +\\ell^- $, $\\ell=e$ or $\\mu$, in terms of form factors. We discuss some\nof the phenomenological models proposed in the literature for the space-like\nregion, and consider their analytical continuation to the time-like region.\nAfter determining the parameters through a fit on the available data, we give\npredictions for the observables which will be experimentally accessible with\nlarge statistics, polarized annihilation reactions.",
