Dispersion - theoretical analysis of the nucleon electromagnetic form factors : Inclusion of time – like data
We update a recent dispersion–theoretical fit to the nucleon electromagnetic form factors by including the existing data in the time–like region. We show that while the time–like data for the proton can be described consistently with the existing world space–like data, this is not the case for the neutron. Another measurement of the process e+e− → n̄n is called for. We furthermore sharpen the pr...
متن کاملTheoretical Descriptions of the Nucleon Electromagnetic Form Factors in the Space- and Time-like regions
The Nucleon electromagnetic form factors (em ff’s) represent a relevant chapter in our path towards the understanding of hadron dynamics. It is striking that, after almost half a century of experimental investigations, this field could still hold a number of surprises (e.g., the intriguing fall-off of the proton charge ff more rapid than the assumed dipole one), or have some kinematical regions...
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 کاملStructure of the Nucleon from Electromagnetic Space-like and Time-like Form Factors
Recent experimental data on space-like and time-like form factors of the nucleon are reviewed in light of a model of the nucleon with an intrinsic (quark-like) structure and a meson cloud. The analysis points to the astonishing result that the proton electric space-like form factor vanishes at Q ∼ 8 (GeV/c) and becomes negative beyond that point. The intrinsic structure is estimated to have a r...
