Parton distributions from the lattice
Nucl.Phys.A755:333-336,2005 I review the current status of lattice calculations for two selected observables related to nucleon structure: the second moment of the unpolarized parton distribution, (u-d), and the first moment of the polarized parton distribution, the non-singlet axial coupling gA.

| description | Nucl.Phys.A755:333-336,2005 I review the current status of lattice calculations for two selected
observables related to nucleon structure: the second moment of the unpolarized
parton distribution, (u-d), and the first moment of the polarized parton
distribution, the non-singlet axial coupling gA. The major challenge is the
requirement to extract them sufficiently close to the chiral limit. In the
former case, there still remains a puzzling disagreement between lattice data
and experiment. For the latter quantity, however, we may be close to obtaining
its value from the lattice in the immediate future. |
