Nucleon-Nucleon Interactions on the Lattice
We consider the nucleon-nucleon potential in quenched and partiallyquenched QCD. The leading one-meson exchange contribution to the potential is found to fall off exponentially at long-distances, in contrast with the Yukawa-type behaviour found in QCD. This unphysical component of the two-nucleon potential has important implications for the extraction of nuclear properties from lattice simulati...
متن کاملNucleon Structure from Lattice QCD
Recent advances in lattice field theory, in computer technology and in chiral perturbation theory have enabled lattice QCD to emerge as a powerful quantitative tool in understanding hadron structure. I describe recent progress in the computation of the nucleon form factors and moments of parton distribution functions, before proceeding to describe lattice studies of the Generalized Parton Distr...
متن کاملNucleon 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...
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 کاملNucleon-nucleon scattering from fully dynamical lattice QCD.
We present results of the first fully dynamical lattice QCD determination of nucleon-nucleon scattering lengths in the 1S0 channel and 3S1 - 3D1 coupled channels. The calculations are performed with domain-wall valence quarks on the MILC staggered configurations with a lattice spacing of b = 0.125 fm in the isospin-symmetric limit, and in the absence of electromagnetic interactions.
