Overview of Nucleon Structure Studies ⋆

A brief overview of the recent activity in the measurement of the elastic electromagnetic proton and neutron form factors is presented. It is discussed how the quality of the data has been greatly improved by performing double polarization experiments, and the role of two-photon exchange processes will be highlighted. The spatial information on the quark charge distribibutions in the nucleon re...

Nucleon 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...

Nucleon Structure from Lattice QCD

We report results on the nucleon structure obtained from the lattice quantum chromodynamics calculation. These include the axial, electromagnetic, πNN , and scalar form factors. The calculation is carried out at β = 6 on a 16 × 24 lattice with 24 quenched gauge configurations. The chiral limit results are extrapolated from several light quark cases. For the disconnected insertion (sea-quark con...
