On Nucleon Electromagnetic Form Factors
A Poincaré covariant Faddeev equation, which describes baryons as composites of confined-quarks and -nonpointlike-diquarks, is solved to obtain masses and Faddeev amplitudes for the nucleon and ∆. The amplitudes are a component of a nucleon-photon vertex that automatically fulfills the Ward-Takahashi identity for on-shell nucleons. These elements are sufficient for the calculation of a quark co...
متن کاملNucleon electromagnetic form factors
Elastic electromagnetic nucleon form factors have long provided vital information about the structure and composition of these most basic elements of nuclear physics. The form factors are a measurable and physical manifestation of the nature of the nucleons’ constituents and the dynamics that binds them together. Accurate form factor data obtained in recent years using modern experimental facil...
متن کاملNucleon Electromagnetic Form Factors
There has been much activity in the measurement of the elastic electromagnetic proton and neutron form factors in the last decade, and the quality of the data has been greatly improved by performing double polarization experiments, in comparison with previous unpolarized data. Here we review the experimental data base in view of the new results for the proton, and neutron, obtained at MIT-Bates...
متن کاملElectromagnetic Form Factors of the Nucleon
Elastic form factors provide information about the low energy structure of composite particles. Recent double polarization coincidence experiments significantly improved our knowledge of proton and neutron form factors. Recoil polarization measurements in the p(~e, e~ p) reaction proved that at momentum transfers above Q ≃ 1.5 (GeV/c) the electric form factor of the proton falls significantly f...
متن کاملMeson Clouds and Nucleon Electromagnetic Form Factors
In contrast with common non-relativistic lore, the usual Sachs form factors are not the Fourier transforms of charge or magnetization densities. Instead, the two-dimensional Fourier transform of the electromagnetic F1 form factor is the charge charge density of partons in the transverse plane. An analysis of the available data for neutron form factors leads to the result that the neutron charge...
