Large cutoff effects of dynamical Wilson fermions
R. Sommer, S. Aoki, M. Della Morte +6
We present and discuss results for cutoff effects in the PCAC masses and the mass dependence of r_0 for full QCD and various fermion actions. Our discussion of how one computes mas…
Non-perturbative renormalization of the axial current with improved Wilson quarks
R. Hoffmann, F. Knechtli, J. Rolf +2
We present a new normalization condition for the axial current, which is derived from the PCAC relation with non-vanishing mass. Using this condition reduces the O(r_0 m) correctio…
Comparison of analytic and numerical results in the XY-model
J. Balog, F. Knechtli, T. Korzec +1
We study the two dimensional XY-model with high precision Monte Carlo techniques and investigate the continuum approach of the step-scaling function of its finite volume mass gap.…
Numerical confirmation of analytic predictions for the finite volume mass gap of the XY-model
Janos Balog, Francesco Knechtli, Tomasz Korzec +1
Recent exact predictions for the massive scaling limit of the two dimensional XY-model are based on the equivalence with the sine-Gordon theory and include detailed results on the…
Dynamical fermions by global acceptance steps
Francesco Knechtli, Ulli Wolff
A study of principle is conducted on the inclusion of the fermionic determinant as a Metropolis acceptance correction. It is carried out in the 2-D Schwinger model to prepare later…
