Electromagnetic Form Factors of Baryons
Electromagnetic form factors of the nucleon and its excitations (baryon resonances) provide a powerful tool to investigate the structure of the nucleon. These form factors can be measured in electroproduction as a function of the four-momentum squared q = −Q of the virtual photon. In this contribution we present a simultaneous study of the elastic form factors of the nucleon and the transition ...
متن کاملElectroweak form factors of non-strange baryons
Abstract. We compute electroweak form factors of the nucleon and photon transition form factors of nonstrange baryon resonances up to the third resonance region in a model with instanton-induced interaction. The calculation is based on the Bethe-Salpeter equation for three light constituent quarks and is fully relativistic (U. Löring et al., Eur. Phys. J. A10, 309 (2001)). Static nucleon proper...
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 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...
