Abstract: The complete knowledge of nucleon form factors is a mandatory pass to deeply understand the dynamics of strong interaction at regimes where QCD is still non perturbative. Phenomenology, i.e., the description of the data by means models based of first principles and depending on physical quantities, represents one of the most powerful tools to attain such a degree of knowledge.

Key words: Nucleon form factors, analyticity, threshold behavior, asymptotic behavior
