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…
Structure of the Nucleon
M. Göckeler, T. R. Hemmert, R. Horsley +5
Generalized parton distributions provide information on the longitudinal and transverse distribution of partons in the fast moving nucleon. Furthermore, they contain information on…
Structure functions and form factors close to the chiral limit from lattice QCD
T. Bakeyev, D. Galletly, M. Göckeler +12
Results for nucleon matrix elements (arising from moments of structure functions) and form factors from a mixture of runs using Wilson, clover and overlap fermions (both quenched a…
Accelerating Hasenbusch's acceleration of Hybrid Monte Carlo
A. Ali Khan, T. Bakeyev, M. Göckeler +6
Hasenbusch has proposed splitting the pseudo-fermionic action into two parts, in order to speed-up Hybrid Monte Carlo simulations of QCD. We have tested a different splitting, also…
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.
Quark spectra and light hadron phenomenology from overlap fermions with improved gauge field action
D. Galletly, M. Gürtler, R. Horsley +8
We present first results from a simulation of quenched overlap fermions with improved gauge field action. Among the quantities we study are the spectral properties of the overlap o…
