Nucleon distribution amplitudes from lattice QCD
Meinulf Göckeler, Roger Horsley, Thomas Kaltenbrunner +8
We calculate low moments of the leading-twist and next-to-leading twist nucleon distribution amplitudes on the lattice using two flavors of clover fermions. The results are present…
Nucleon electromagnetic form factors with Wilson fermions
M. Gockeler, Ph. Hagler, R. Horsley +9
The nucleon electromagnetic form factors continue to be of major interest for experimentalists and phenomenologists alike. They provide important insights into the structure of nuc…
Decay constants of charm and beauty pseudoscalar heavy-light mesons on fine lattices
A. Ali Khan, V. Braun, T. Burch +4
We compute decay constants of heavy-light mesons in quenched lattice QCD with a lattice spacing of a ~ 0.04 fm using non-perturbatively O(a) improved Wilson fermions and O(a) impro…
Transverse spin structure of the nucleon from lattice QCD simulations
M. Göckeler, Ph. Hägler, R. Horsley +7
We present the first calculation in lattice QCD of the lowest two moments of transverse spin densities of quarks in the nucleon. They encode correlations between quark spin and orb…
Chiral extrapolations
M. Göckeler
The comparison of chiral perturbation theory formulae with data from lattice QCD simulations is discussed. Observables in the pion sector as well as in the baryon sector are consid…
