Vacuum Polarisation and Hadronic Contribution to muon g-2 from Lattice QCD
M. Göckeler, R. Horsley, W. Kürzinger +3
We compute the vacuum polarisation on the lattice in quenched QCD using non-perturbatively improved Wilson fermions. Above Q^2 of about 2 GeV^2 the results are very close to the pr…

Vacuum polarisation and the muon g-2 in lattice QCD
M. Göckeler, R. Horsley, W. Kürzinger +3
We measure the hadronic contribution to the vacuum polarisation tensor, and use it to estimate the hadronic contribution to (g-2)_mu, the muon anomalous magnetic moment.

The Polarized Structure Function g_2: A Lattice Study Revisited
M. Göckeler, R. Horsley, W. Kürzinger +3
A recent lattice calculation of the spin-dependent structure function g_2 is revisited. It has been recognized that the twist-three operator, which gives rise to d_2, mixes non-per…
