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…
Structure of the Pion from Full Lattice QCD
D. Brömmel, M. Diehl, M. Göckeler +7
Moments of generalised parton distributions can be related to off-forward matrix elements of local operators. We calculate a few of the leading twist matrix elements for the pion o…
Quark helicity flip generalized parton distributions from two-flavor lattice QCD
M. Gockeler, Ph. Hagler, R. Horsley +5
We present an initiatory study of quark helicity flip generalized parton distributions (GPDs) in n_f=2 lattice QCD, based on clover-improved Wilson fermions for a large number of c…
Investigation of the Second Moment of the Nucleon's g1 and g2 Structure Functions in Two-Flavor Lattice QCD
M. Göckeler, R. Horsley, D. Pleiter +5
The reduced matrix elements a_2 and d_2 are computed in lattice QCD with N_f=2 flavors of light dynamical (sea) quarks. For proton and neutron targets we obtain as our best estimat…
A Determination of the Lambda Parameter from Full Lattice QCD
M. Göckeler, R. Horsley, A. C. Irving +4
We present a determination of the QCD parameter Lambda in the quenched approximation (n_f=0) and for two flavours (n_f=2) of light dynamical quarks. The calculations are performed…
Generalized parton distributions and transversity from full lattice QCD
M. Gockeler, Ph. Hagler, R. Horsley +5
We present here the latest results from the QCDSF collaboration for moments of generalized parton distributions and transversity in two-flavour QCD, including a preliminary analysi…
