Scaling test of two-flavor O(a)-improved lattice QCD
Michele Della Morte, Patrick Fritzsch, Harvey B. Meyer +5
We report on a scaling test of several mesonic observables in the non-perturbatively O(a) improved Wilson theory with two flavors of dynamical quarks. The observables are construct…
Cluster simulation of two-dimensional relativistic fermions
Ulli Wolff
The (discrete) Gross-Neveu model is studied in a lattice realization with an N-component Majorana Wilson fermion field. It has an internal O(N) symmetry in addition to the euclidea…
Spectral properties of the non-hermitian Wilson-Dirac operator in the Schroedinger functional
Oliver Witzel, Shinji Takeda, Ulli Wolff
We report on some preparatory investigations for the simulation of the QCD Schroedinger functional with a non-hermitian polynomial hybrid Monte Carlo algorithm. The complex spectru…
Restoring chiral symmetry to O(a^2) for dynamical Wilson fermions
Roland Hoffmann, Michele Della Morte, Francesco Knechtli +2
We present results for the non-perturbative determination of the improvement and renormalization factors of the isovector axial current for lattice QCD with two flavors of dynamica…
