Generalized Parton Distributions in Full Lattice QCD
M. Göckeler, Ph. Hägler, R. Horsley +5
We present recent results on generalized parton distributions from dynamical lattice QCD calculations. Our set of twelve different combinations of couplings and quark masses allows…
Helicity Dependent and Independent Generalized Parton Distributions of the Nucleon in Lattice QCD
Ph. Hagler, J. W. Negele, D. B. Renner +3
A complete description of the nucleon structure in terms of generalized parton distributions (GPDs) at twist 2 level requires the measurement/computation of the eight functions H,…
Hadronic physics with domain-wall valence and improved staggered sea quarks
D. B. Renner, W. Schroers, R. Edwards +6
With the advent of chiral fermion formulations, the simulation of light valence quarks has finally become realistic for numerical simulations of lattice QCD. The simulation of ligh…
Axial and tensor charge of the nucleon with dynamical fermions
A. Ali Khan, M. Göckeler, P. Hägler +9
We present preliminary results for the axial and tensor charge of the nucleon obtained from simulations with N_f=2 clover fermions. A comparison with chiral perturbation theory is…
Form factor decomposition of generalized parton distributions at leading twist
Ph. Hagler
We extend the counting of generalized form factors presented in PRD63(2000) by Ji and Lebed to the axial vector and the tensor operator at twist-2 level. Following this, a paramete…
