Electromagnetic Hadronic Form-Factors
The determination of light hadron physics properties is of considerable interest to experimental labs such as Jefferson Lab. Many quantities, such as hadron form-factors and generalized structure functions, are not well understood theoretically. The available and forthcoming high precision experimental data presents considerable challenges and many opportunities for corresponding lattice calcul...
متن کاملHadronic Electromagnetic Form Factors and Color Transparency
We review the current status of electromagnetic form factor calculations in perturbative QCD. There is growing evidence that factorization prescriptions involving a transverse coordinate integration, such as that of Li and Sterman, are more appropriate than the prescription of LePage and Brodsky. Color transparency is naturally described within the formalism. We report the first explicit calcul...
متن کاملDisconnected Electromagnetic Form Factors
Preliminary results of a calculation of disconnected nucleon electromagnetic factors factors on the lattice are presented. The implementation of the numerical subtraction scheme is outlined. A comparison of results for electric and magnetic disconnected form factors on two lattice sizes with those of the Kentucky group is presented. Unlike previous results, the results found in this calculation...
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...
