Electroproduction of the N*(1535) resonance at large momentum transfer
V. M. Braun, M. Göckeler, R. Horsley +11
We report on the first lattice calculation of light-cone distribution amplitudes of the N*(1535) resonance, which are used to calculate the transition form factors at large momentu…
Soffer Bound and Transverse Spin Densities from Lattice QCD
M. Diehl, M. Gockeler, Ph. Hagler +6
Generalized transversity distributions encode essential information on the internal structure of hadrons related to transversely polarized quarks. Lattice QCD allows us to compute…
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…
A lattice determination of moments of unpolarised nucleon structure functions using improved Wilson fermions
M. Göckeler, R. Horsley, D. Pleiter +2
Within the framework of quenched lattice QCD and using O(a) improved Wilson fermions and non-perturbative renormalisation, a high statistics computation of low moments of the unpol…
Determination of Light and Strange Quark Masses from Full Lattice QCD
M. Göckeler, R. Horsley, A. C. Irving +4
We compute the light and strange quark masses m_l = (m_u+m_d)/2 and m_s, respectively, in full lattice QCD with N_f=2 flavors of light dynamical quarks. The renormalization constan…
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…
