Quark masses from quenched overlap fermions
Martin Gürtler, Thomas Streuer, Gerrit Schierholz +3
We compute light and strange quark masses for quenched overlap fermions at two values of the gauge coupling. The renormalisation is done non-perturbatively. We test the predictions…
Nucleon structure from generalized parton distributions in lattice QCD
M. Gockeler, Ph. Hagler, R. Horsley +5
This talk presents results from the QCDSF-UKQCD collaboration for moments of leading twist generalized parton distributions in two-flavor lattice QCD based on O(a) improved Wilson…
Perturbative Renormalisation for Low Moments of Generalised Parton Distributions with Clover Fermions
M. Gockeler, R. Horsley, H. Perlt +4
We present the non-forward quark matrix elements of operators with one and two covariant derivatives needed for the renormalisation of the first and second moments of generalised p…
Second moment of the pion's distribution amplitude
M. Göckeler, R. Horsley, D. Pleiter +5
We present preliminary results from the QCDSF/UKQCD collaborations for the second moment of the pion's distribution amplitude with two flavours of dynamical fermions. We use nonper…
The axial charge of the nucleon on the lattice and in chiral perturbation theory
A. Ali Khan, M. Göckeler, P. Hägler +10
We present recent Monte Carlo data for the axial charge of the nucleon obtained by the QCDSF-UKQCD collaboration for N_f=2 dynamical quarks. We compare them with formulae from chir…
Nucleon Structure from Quenched Overlap Fermions
D. Galletly, M. Gürtler, R. Horsley +6
We compute the lowest moments of the nucleon's structure functions using quenched overlap fermions at two different lattice spacings. The renormalisation is done nonperturbatively…
