Disconnected 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 کاملElectromagnetic 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 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 کاملOn 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...
