A description of the ratio between electric and magnetic proton form factors by using space-like, time-like data and dispersion relations
نویسندگان
چکیده
We use the available information on the ratio between the electric and magnetic proton form factors coming from recently published space-like data and from the few available time-like data. We apply a dispersive procedure on these data to evaluate the behaviour of this ratio, as a complex function, for all values of q.

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...

The process p̄p → ee is considered in the general case of polarized initial particles. A relation between the difference of the phases of the electromagnetic form factors GM and GE in the time-like region and measurable asymmetries is derived. It is shown that the moduli of the form factors can be determined from measurements of the total unpolarized cross section and of the integral asymmetry f...
