The Vacuum Polarization: Power Corrections beyond OPE ?
M. Gockeler, R. Horsley, W. Kurzinger +4
We compute the vacuum polarization on the lattice using non-perturbatively O(a) improved Wilson fermions. The result is compared with the operator product expansion (OPE).
A lattice calculation of the nucleon's spin-dependent structure function g_2 revisited
M. Gockeler, R. Horsley, W. Kurzinger +5
Our previous calculation of the spin-dependent structure function g_2 is revisited. The interest in this structure function is to a great extent motivated by the fact that it recei…
Light quark masses for dynamical, non-perturbatively O(a) improved Wilson fermions
D. Pleiter, QCDSF Collaboration, UKQCD Collaboration
We present results for the light quark masses in lattice QCD with two degenerate flavours of dynamical fermions. We used configurations generated by the UKQCD and QCDSF collaborati…
Four-quark operators in hadrons
S. Capitani, M. Gockeler, R. Horsley +8
We present calculations of matrix elements of 4-quark operators in the pion and in the nucleon extracted from quenched Monte Carlo simulations at beta = 6.0 using Wilson fermions.…
Quenched QCD near the chiral limit
M. Gockeler, R. Horsley, D. Petters +3
A numerical study of quenched QCD for light quarks is presented using O(a) improved fermions. Particular attention is paid to the possible existence and determination of quenched c…
