Preparing for N_f=2 simulations at small lattice spacings
M. Della Morte, P. Fritzsch, B. Leder +6
We discuss some large effects of dynamical fermions. One is a cutoff effect, others concern the contribution of multi-pion states to correlation functions and are expected to survi…
Monte-Carlo simulation of the chiral Gross-Neveu model
Tomasz Korzec, Francesco Knechtli, Ulli Wolff +1
We investigate the two flavor chiral Gross-Neveu model in the Schroedinger functional on the lattice. The procedure necessary to recover chiral symmetry in the continuum limit of t…
Non-perturbative quark mass renormalization in two-flavor QCD
Michele Della Morte, Roland Hoffmann, Francesco Knechtli +4
The running of renormalized quark masses is computed in lattice QCD with two flavors of massless O(a) improved Wilson quarks. The regularization and flavor independent factor that…
Dynamical fermions as a global correction
Francesco Knechtli, Ulli Wolff
In the simplified setting of the Schwinger model we present a systematic study on the simulation of dynamical fermions by global accept/reject steps that take into account the ferm…
Running quark mass in two flavor QCD
F. Knechtli, M. Della Morte, J. Rolf +3
We present first results for the step scaling function sigma_P of the renormalization factor Z_P of the pseudoscalar density. The simulations are performed within the framework of…
