Implication of the proton electric FF space-like behavior puzzle in various physical phenomena
Abstract
Description
By means of the 10-resonance unitary and analytic model of nucleon electromagnetic structure it is demonstrated that the JLab proton polarization data on the ratio $μ_p G_{Ep}(Q^2)/G_{Mp}(Q^2)$ are consistent with all form factor properties, however, they strongly require an existence of the zero in G_{Ep}(Q^2) around Q^2=13 GeV^2. As a result there are two contradicting behaviors of G_{Ep}(Q^2) in space-like region. Consequences of this phenomenon on the charge distribution within the proton, on the saturation of the new proton-neutron q^2-dependent sum rule, on the behavior of strange nucleon form factors and the deuteron elastic structure functions through the impulse approximation are investigated.
