A special eight-resonance unitary and analytic model of nucleon electromagnetic structure is used to analyze first the classical proton form factor data obtained by the Rosenbluth technique, and then also the contradictory JLab proton polarization data on the ratio μp G Ep(Q 2)/G Mp(Q 2) , with the aim to investigate the implications of the latter for the behavior of strange nucleon form factors.
