متن کاملNucleon electromagnetic form factors from lattice QCD
It is imperative that lattice QCD serve to develop our understanding of hadron structure and, where possible, to guide the interpretation of experimental data. There is now a great deal of effort directed at the calculation of the electroweak form factors of the nucleon, where for example, measurements at Jefferson Laboratory have recently revealed surprising behaviour in the ratio GE/GM. While...
متن کاملNucleon and Pion-nucleon Form Factors from Lattice Qcd
The isovector Nucleon electromagnetic form factors GE(q ) and GM(q ) are evaluated in Lattice QCD using Wilson fermions. A lattice of spatial extent 3 fm is used in the quenched theory allowing the extraction of the form factors for momentum transfer squared between 0.1 and 2 GeV for lowest pion mass of about 400 MeV. The calculation is also performed using two degenerate dynamical flavors of W...

متن کاملElectromagnetic nucleon form factors from QCD sum rules
The electromagnetic form factors of the nucleon, in the space-like region, are determined from three-point function Finite Energy QCD Sum Rules. The QCD calculation is performed to leading order in perturbation theory in the chiral limit, and to leading order in the non-perturbative power corrections. The results for the Dirac form factor, F1(q 2), are in very good agreement with data for both ...
