متن کاملNucleon axial charge in 2+1-flavor dynamical DWF lattice QCD
The current status of some nucleon isovector observables, the vector charge, gV , axial charge, gA, quark momentum fraction, 〈x〉u−d , and quark helicity fraction, 〈x〉∆u−∆d , calculated using recent RBC/UKQCD 2+1-flavor dynamical domain-wall fermions (DWF) lattice QCD ensembles are reported: with Iwasaki gauge action at inverse lattice spacing, a−1, of about 1.7 GeV, linear lattice extent, L, of...
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 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...
