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…
Light baryon masses with dynamical twisted mass fermions
C. Alexandrou, R. Baron, B. Blossier +17
We present results on the mass of the nucleon and the Delta using two dynamical degenerate twisted mass quarks and the tree-level Symanzik improved gauge action. The evaluation is…
Localized eigenmodes of the overlap operator and their impact on the eigenvalue distribution
Anna Hasenfratz, Roland Hoffmann, Stefan Schaefer
In a system where chiral symmetry is spontaneously broken, the low energy eigenmodes of the continuum Dirac operator are extended. On the lattice, due to discretization effects, th…
Parameters of the lowest order chiral Lagrangian from fermion eigenvalues
Thomas DeGrand, Stefan Schaefer
Recent advances in Random Matrix Theory enable one to determine the pseudoscalar decay constant from the response of eigenmodes of quenched fermions to an imaginary isospin chemica…
Exploring the structure of the quenched QCD vacuum with overlap fermions
E. -M. Ilgenfritz, K. Koller, Y. Koma +3
Overlap fermions have an exact chiral symmetry on the lattice and are thus an appropriate tool for investigating the chiral and topological structure of the QCD vacuum. We study va…
Understanding nucleon structure using lattice simulations
Wolfram Schroers
This review focuses on the discussion of three key results of nucleon structure calculations on the lattice. These three results are the quark contribution to the nucleon spin, J_q…
